UL316
DESCRIPTION The UL316 is a pact LED controller and driver that interface microprocessors to LED displays through a serial 3-wire interface. It drives LED connected in mon 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 m A 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...
