DESCRIPTION
Designed to interface logic to a wide variety of high
current, high voltageloads, thesedeviceseach 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 followerconfigurations.Inputsof 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
ULN2070Binclude a predriverstageto reduceload-
ing on the control logic.
