SERIAL-INTERFACED 6-DIGIT LED CONTROLLER IC WITH KEYSCAN * 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 * 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 |
