Product Summary

The ULN2003ADR is a high-voltage high-current Darlington transistor array. The ULN2003ADR 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 applications of the ULN2003ADR include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
