ULN2070B

50V - 1.5A四联复合晶体管开关系列 50V - 1.5A QUAD DARLINGTON SWITCHES

DESCRIPTION

Designed to interface logic to a wide variety of high current, high voltageloads,these devices 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 in tegral 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 compatible with popular 5 V logic families and the ULN2067B, ULN2071B and ULN2077B are compatible with 6-15 VCMOS and PMOS. The ULN2069B and ULN2071B include a predriver stage to provide extragain, reducing the load on control logic.
