SERIAL-INTERFACED 14-DIGIT LED CONTROLLER IC WITH KEYSCAN

The UL319B is a compact LED controller and driver thatinterface microprocessors to LED displays through a serial3-wire interface. It drives LED connected in common anodeconfiguration. The UL319B drives up to 112 discrete LEDsin 14 segment/8 digit configuration while functioning from asupply voltage LED driver with 22 outputs (14 segments/8 digits) Output pins connected directly to the LEDs Key-scanning (8 x 2 matrix) 3-wire serial bus interface (CLK, STB, DI/O) 8-step dimming circuit to control the overall display brightness Inputs with Schmitt trigger give superior noise immunity 5.0 V (± 10&;
