8 Darlington Arrays in 18-Pin DIP Package part # ULN2803A. Perfect for running relays and high-power devices up to 500mA and up to 50V!

Please note, this is an 'open collector' driver - it can only be used to connect the load to ground and there will be a 1 Volt (or more) 'drop' across the internal transistors. The inputs can be driven by 3.3V or 5V logic. Fits nicely in any breadboard or perfboard.
