Description

Designed to interface logic to a wide variety of high current, high voltage loads, the ULN2074B-02 is an electronic component model in the IC Chips product category. It contains four NPN darlington switches that can deliver up to 1.5 A with a minimum breakdown of 80 V and a sustaining voltage of 50 V. The ULN2065B, ULN2067B, ULN2069B, and ULN2071B versions include integral suppression diodes for inductive loads and have common emitters. On the other hand, the ULN2075B and ULN2077B versions feature isolated darlington pinouts and are suitable for emitter follower configurations. The ULN2065B, ULN2069B, and ULN2075B versions are compatible with popular 5V logic families, while the ULN2067B, ULN2071B, and ULN2077B versions are compatible with 6-15V CMOS and PMOS. Furthermore, the ULN2069B and ULN2071B versions include a predriver stage to provide extra gain, reducing the load on control logic.
