Description
General part information
ULN2803C Series
The ULN2803C device is a 50V, 500mA 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 500mA. The Darlington pairscan be connected in 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 device has a 2.7kΩ series base resistor for each Darlington pair for operation directly with TTL or 5V CMOS devices.
