ULN2004AI,pdf(HIGH-VOLTAGE HIG

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. series base resistor for each Darlington pair for operaTIon directly with TTL or 5-V CMOS devices.
