DESCRIPTION/ORDERING INFORMATION
The ULN2003AI 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.
Applications include relay drivers, hammer drivers,
lamp drivers, display drivers (LED and gas
discharge), line drivers, and logic buffers.
