Designed to interface logic to a wide variety of high current, high voltageloads,thesedevices each contain four NPN darlington switches delivering up to 1.5 A with a specified minimum breakdown of 80 V and a sustaining voltage of 50 V. The ULN2065B, ULN2067B, ULN2069B and ULN2071B contain integral suppression diodes for inductive loads and have common emitters ; the ULN2075B and ULN2077B feature isolated darlington pinouts and are intended for applications such as emitter follower configurations. Inputs of the ULN2065B, ULN2069B and ULN2075B are mpatible with popular 5 V logic families and the ULN2067B, ULN2071B and ULN2077B are compatible with 6- 15 VCMOS and PMOS. The ULN2069B and ULN2071Binclude a predriver stage to provide extragain, reducing the load on control logic.
