FEATURES
DESCRIPTION
The ULN2803A device is a high-voltage, high-current
Darlington transistor array. The device consists of
eight npn Darlington pairs that feature high-voltage
outputs with common-cathode clamp diodes for
switching inductive loads. The collector-current rating
of each Darlington pair is 500 mA. The Darlington
pairs may be connected in parallel for higher current
capability.

Relay-Driver Applications
Applications include relay drivers, hammer drivers,
lamp drivers, display drivers (LED and gas
discharge), line drivers, and logic buffers. The
ULN2803A device has a 2.7-kΩ series base resistor
for each Darlington pair for operation directly with
TTL or 5-V CMOS devices.
