DESCRIPTION
Designed to interface logic to a wide variety of high
current, high voltageloads, these devices each con-
tain 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 fol-
lower 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 ex-
tragain, reducing the load on control logic.
