ULN2803A,pdf(DARLINGTON TRANSI

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.
