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
* 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 V_CC
* Drives common-anode LED digits
* Built-in power on reset and soft-start circuits
