3 Description
The ULN2803A device is a 50 V, 500 mA 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.
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.
