ULN2065B - ULN2067B ULN2069B - ULN2071B ULN2075B - ULN2077B 80 V - 1.5 A QUAD DARLINGTON SWITCHES . . . . . . OUTPUT CURRENT TO 1.5 A EACH DARLINGTON MINIMUM BREAKDOWN 80 V SUSTAINING VOLTAGE AT LEAST 50 V INTEGRAL SUPPRESSION DIODES (ULN2065B, ULN2067B, ULN2069B and ULN2071B) ISOLATEDDARLINGTON PINOUT (ULN2075B and ULN2077B) VERSIONS COMPATIBLE WITH ALL POPULAR LOGIC FAMILIES 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 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 compatible with popular 5 V logic families and the ULN2067B, ULN2071B and ULN2077B are compatible with 615 VCMOS and PMOS. The ULN2069B and ULN2071B include a predriver stage to provide extragain, reducing the load on control logic.
