description/ordering information
The ULN2803A 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.

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