ULN2803 8-Channel Darlington Transistor Array IC DIP-18 (Min 5 Pcs)

The ULN2803 is an 8-channel NPN Darlington transistor array in DIP-18 package — the 8-channel big brother to the ULN2003. Each channel sinks up to 500mA at 50V with built-in flyback diodes, and the pinout is optimized for direct interfacing with 8-bit microcontrollers and port expanders. Sold in a minimum of 5 pieces.
