HTCSEMI-HT2803ARWZ

HT2803A  

8CH Darlington Sink Driver  

The HT2803A&HT2804A

 

are high-voltage, high-current  

darlington drivers comprised of eight NPN darlington pairs.  

All units feature integral clamp diodes for switching  

indicative loads.  

HT2803AN  

HT2804AN  

Application include relay, hammer, lamp and display (LED)  

drivers.

* Stresses beyond

those listed under “absolute maximum ratings” may cause permanent damage to the device.  

These are stress ratings only and functional operation of the device at these or any other conditions beyond those  

indicated under “recommended operating conditions” is

not implied.  

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Precautions for Using  

Utmost care is necessary in the design of output line, COMMON and GND line since IC may be destroyed  

due to short-circuit between outputs, air contaminaton fault, or fault by improper grounding.
