ST ULN2803A Darlington Transistor Array (Pk of 2)

Manufactured by ST Microlectronics - DIL18 Package

DESCRIPTION

The ULN2803A device 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.
