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
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.
