ULN2803AG is a high-voltage, high-current Darlington array composed of eight NPN Darlington tubes. All cells share the emitter, and each cell uses an open collector output. Each pair of Darlingtons is connected in series with a 2.7K base resistor, which is directly compatible with TTL and 5VCMOS circuits, and can directly process data that previously required standard logic buffers to process. ULN2803AG has high working voltage, large working current, sink current up to 500mA, and can withstand 50V voltage in the off state, and the output can also run in parallel under high load current, which provides a good solution for multi-interface drive circuits .
