Description:

The ULN2803C device is a 50-V, 500-mA Darlingtontransistor array. The device consists of eight NPNDarlington pairs that feature high-voltage outputs withcommon-cathode clamp diodes for switching inductiveloads. The collector-current rating of each Darlingtonpair is 500 mA. The Darlington pairscan be connectedin parallel for higher current capability.Applications include relay drivers, hammer drivers,lamp drivers, display drivers (LED and gas discharge),line drivers, and logic buffers. The ULN2803C devicehas a 2.7-kΩ series base resistor for each Darlingtonpair for operation directly with TTL or 5-V CMOSdevices.
