UL319B Preliminary LINEAR INTEGRATED CIRCUIT SERIAL-INTERFACED 14-DIGIT LED CONTROLLER IC WITH KEYSCAN  DESCRIPTION The UL319B 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 UL319B drives up to 112 discrete LEDs in 14 segment/8 digit configuration while functioning from a supply voltage of 5.
0V.
SOP-32  FEATURES * 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  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UL319BG-S32-R UL319BG-S32-R * Inputs with Schmitt trigger give superior noise immunity * 5.
0 V (± 10%) for VDD * Drives common-anode LED digits * Built-in power on reset circuits * Built-in pull-up resistor (CLK,STB,DI/O) Package SOP-32 Packing Tape Reel UL319BG-S32-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) S32: SOP-32 (3) G: Halogen Free and Lead Free, L: Lead Free  MARKING 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 UTC UL319B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Date Code L: Lead Free G: Halogen Free Lot Code www.
