Eco Plan – The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) – please check

for the latest availability  
information and additional product content details.  
TBD:
The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS):
TI’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt):
This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based
 
die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br):
TI defines “Green” to mean Pb-Free (RoHS compatible), and free of Bromine (Br)
 
and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  

(3)

MSL, Peak Temp. – The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  

(4)

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  

(5)

Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a “~” will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  

(6)

Lead/Ball Finish – Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish  
value exceeds the maximum column width.

IMPORTANT NOTICE  
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its  
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers  
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.  
TI’s published terms of sale for semiconductor products (

) apply to the sale of packaged integrated  
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and  
services.  
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is  
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced  
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements  
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the  
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.  
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers  
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have  
full and exclusive responsibility to assure the safety of Designers’ applications and compliance of their applications (and of all TI products  
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with  
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous  
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and  
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will  
thoroughly test such applications and the functionality of such TI products as used in such applications.  
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,  
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to  
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any  
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource  
solely for this purpose and subject to the terms of this Notice.  
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI  
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,  
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically  
described in the published documentation for a particular TI Resource.  
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that  
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE  
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY  
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or  
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR  
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO  
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF  
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL  
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,  
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF  
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,  
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN  
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN  
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.  
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949  
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.  
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such  
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards  
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must  
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in  
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.  
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life  
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all  
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.  
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).  
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications  
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory  
requirements in connection with such selection.  
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-  
compliance with the terms and provisions of this Notice.
