UL318B
DESCRIPTION
The UL318B is a pact LED controller and driver that interface microprocessors to LED displays through a serial 3-wire interface. It drives LED connected in mon anode configuration. The UL318B drives up to LEDs in 8 segment/6 digit~10 segment/4 digit configuration while functioning from a supply voltage of 5.0V.
