ULN2064B, ULN2066B
ULN2068B, ULN2074B
50 V - 1.5 A quad Darlington switches
Features
■ Output current to 1.5 A for each Darlington
■ Minimum breakdown 50 V
■ Sustaining voltage at least 35 V
■ Integral suppression diodes (ULN2064B,
ULN2066B and ULN2068B
■ Isolated Darlington pinout (ULN2074B)
■ Versions compatible with all popular logic
families
Description
Designed to interface logic to a wide variety of
high current, high voltage loads, these devices
each contain 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 and ULN2068B contain integral
suppression diodes for inductive loads have
common emitters. The ULN2074B feature
isolated Darlington pinouts and is intended for
PowerDIP-16
applications such as emitter follower
configurations. Inputs of the ULN2064B,
ULN2068B and ULN2074B are compatible with
popular 5 V logic families and the ULN2066B are
compatible with 6 - 15 V CMOS and PMOS. Type
ULN2068B includes a pre-driver stage to reduce
loading on the control logic.
