UL316 Datasheet (UTC) - 6-DIGIT LED CONTROLLER

UL316, 6-DIGIT LED CONTROLLER

The UL316 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 UL316 drives up to 48 discrete LEDs in 8 segment/6 digit configuration while functioning from a supply voltage
