3 Description
The ULN2003B device is a high-voltage, high-current
Darlington transistor array. This device consists of
seven NPN Darlington pairs that feature high-voltage
outputs with common-cathode clamp diodes for
switching inductive loads. The collector-current rating
of a single Darlington pair is 500 mA. The Darlington
pairs can be paralleled for higher current capability.
The ULN2003B has a 2.7-kΩ series base resistor for
each Darlington pair for operation directly with TTL or
CMOS devices.
