The ULN2004AI is a high-voltage, high-current
E8
9 COM
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.
The ULN2004AI has a 10.5-kΩ series base resistor for each Darlington pair for operation directly with TTL or
5-V CMOS devices.
