The ULN2803A is an 8-channel Darlington transistor array designed for high-voltage and high-current applications. Each channel features a 500-mA collector current rating and 50-V outputs, with integrated common-cathode clamp diodes for switching inductive loads. The device includes a 2.7-k series base resistor per channel, enabling direct operation with TTL or 5-V CMOS logic. Its versatility makes it suitable for driving relays, lamps, stepper motors, and display drivers, among other applications.
