Texas Instruments ULN2004AI

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.
