Description  

Designed to interface logic to a wide variety of  

high current, high voltage loads, these devices  

each contain four NPN Darlington switches  

delivering up to 1.5 A with a specified minimum  

breakdown of 50 V and a sustaining voltage of 35  

V measured at 100 mA. The ULN2067B and  

ULN2069B contain integral suppression diodes  

for inductive loads have common emitters. The  

ULN2075B feature isolated Darlington pinouts  

and is intended for applications such as emitter  

follower configurations.  

Inputs of the ULN2065B, ULN2069B and  

ULN2075B are compatible with popular 5 V logic  

families and the ULN2067B is compatible with 6-  

15 V CMOS and PMOS.

T

pe ULN2069B  

includes a pre-driver stage to reduce loading on  

the control logic.
