Part Details:

ULN2064B - ULN2066B ULN2068B - ULN2070B ® ULN2074B - ULN2076B 50V - 1.5A QUAD DARLINGTON SWITCHES .OUTPUT CURRENT TO 1.5 A EACH DAR- LINGTON .MINIMUM BREAKDOWN 50 V .SUSTAINING VOLTAGE AT LEAST 35 V .INTEGRAL SUPPRESSION DIODES (ULN2064B, ULN2066B, ULN2068B andULN2070B) .ISOLATED DARLINGTON PINOUT (ULN2074B, ULN2076B) .VERSIONS COMPATIBLE WITH ALL POPU- LAR LOGIC FAMILIES DESCRIPTION Designed to interface logic to a wide variety of highcurrent, high voltage loads, these devices each con-tain four NPN darlington switches delivering up to POWERDIP 1.5 A with a specified minimum breakdown of 50 V 12 + 2 + 2 and a sustaining voltage of 35 V measured at 100mA. The ULN2064B, ULN2066B, ULN2068B andULN2070B contain integral suppression diodes forinductive loads have common emitters. TheULN2074B and ULN2076B feature isolated dar-lington pinouts and are intended for applicationssuch as emitter follower configurations. Inputs of theULN2064B, ULN2068B and ULN2074B are com-patible with popular 5 V logic families and theULN2066B and ULN2076B are compatible with 6-15 V CMOS and PMOS. Types ULN2068B andULN2070B include a predriver stage to reduce load-ing on the control logic.
