description/ordering information

The ULN2004AI 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.

The ULN2004AI has a 10.5-k

Ω series base resistor for each Darlington pair for operation directly with TTL or

5-V CMOS devices.
