DESCRIPTION

Designed to interface logic to a wide variety of high

current, high voltage loads, these devices each con-

tain four NPN darlington switches delivering up to

1.5 A with a specified minimum breakdown of 50 V

and a sustaining voltage of 35 V measured at 100

mA. The ULN2064B, ULN2066B, ULN2068B and

ULN2070B contain integral suppression diodes for

inductive loads have common emitters. The

ULN2074B and ULN2076B feature isolated dar-

lington pinouts and are intended for applications

such as emitter follower configurations. Inputs of the

ULN2064B, ULN2068B and ULN2074B are com-

patible with popular 5 V logic families and the

ULN2066B and ULN2076B are compatible with 6-

15 V CMOS and PMOS. Types ULN2068B and

ULN2070B include a predriver stage to reduce load-

ing on the control logic.
