The TPIC6C595N is a 20 pin dip high power 8 bit shift register.
Simple shift register IC that can control high-voltage/high-current devices directly! Clock in data and latch it to control devices like relays, motors, high-current optical devices, and more! Each channel can sink 150mA continuous, 500mA max. They cannot source current so they should be connected to LED cathodes. This makes them ideal for use with LED matrices where you end up sinking 8 or more LEDs at once.
They are not the same pinout as '595s so check the datasheet!
