Overview
UNISONIC TECHNOLOGIES CO.
,LTD UL316 LINEAR INTEGRATED CIRCUIT SERIAL-INTERFACED 6-DIGIT LED CONTROLLER IC WITH KEYSCAN  DESCRIPTION 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 of 5.
0V.
SOP-24  FEATURES * LED driver with 14 outputs (8 segments/6 digits)×40 mA load current capability for each segment * Output pins connected directly to the LEDs or can be open-drain * Key-scanning (8 x 2 matrix) * 3-wire serial bus interface (CLK, STB, DIN/DOUT) * 8-step dimming circuit to control the overall display brightness  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UL316L-S24-R UL316G-S24-R * Single external resistor for output current setting * Inputs with Schmitt trigger give superior noise immunity * A single LED digit output (DIG1_LED) can be used to drive up to 8 discrete LEDs * 8-step dimming circuit to control brightness of individual LEDs for LED digit * 5.
0 V (± 10%) for VCC * Drives common-anode LED digits * Built-in power on reset and soft-start circuits Package SOP-24 Packing Tape Reel  MARKING www.
