Seven Darlington driver channels in one 16-pin DIP, sitting between a microcontroller and things that draw real current: relays, solenoids, small motors, filament lamps and the 28BYJ-48 stepper. Each channel sinks up to 500 mA at up to 50 V, and each input already has a 2.7 kohm base resistor so a 5 V logic pin drives it directly. Pin 9 brings out common-cathode flyback diodes, so inductive loads have somewhere for their spike to go.

Key features

  • Seven channels, 500 mA each
  • Outputs rated to 50 V
  • Built-in flyback diodes on the COM pin (pin 9)
  • 2.7 kohm input resistors - drive straight from 5 V logic
  • Saturation 1.0 V typ at 200 mA
  • Channels can be paralleled for more current
  • 16-pin DIP
