DESCRIPTION
The UL319C is a compact LED controller and driver that
interface microprocessors to LED displays through a serial
3-wire interface. It drives LED connected in common anode
configuration. The UL319C drives up to 80 discrete LEDs in
10 segment/8 digit configuration while functioning from a
supply voltage of 5.0V.
