DESCRIPTION
Designed to interface l ogic to a wi de v ari et y of high
current, high v oltage loads, these devic es each contain four NPN darlington switches delivering up to
1.5 A with a s pec ified 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 darlington pinouts and are intended for applications
such as emitter follow er configur ations. Inpu ts of the
ULN2064B, ULN2068B and ULN2074B are compatible with popular 5 V logic families and the
ULN2066B and ULN2076B are compatible with 615 V CMOS and PMOS. Types ULN2068B and
ULN207 0B include a predriver s tage to reduce loading on the c ontr ol logic.

1. Input voltage is with reference to the substrate (no connection to any other pins) for the ULN2074B and ULN2076B
reference is ground for all other types.
2. Input current may be limited by maximum allowable input voltage.
