ULN2803A DARLINGTON ARRAY DRIVER IC 18-SOP

The ULN2803 is high-voltage, high-current darlington driver IC
composed of 8 NPN darlington pairs. All units share the emitter in
common, and each unit adopts open-collector output. A 2.7KΩ resistor is
connected to each darlington pair in serial, which is compatible with TTL
and 5V CMOS for data processing without logic buffer.
Sink current of ULN2803 is up to 500mA, when it is off state, the
withstand voltage is 50V and the output can runs with high load current,
which provides solutions for various interface.
