4 / 17 page DM115B 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. 8-BIT CONSTANT CURRENT LED DRIVERS with 3.3V~5V supply voltage Version:A.001 Page 3 Timing Diagram (Note) Latches are level sensitive (not edge triggered). LATCH-terminal = H level, latches become transparent; LATCH-terminal = L level, latches hold data. ENABLE-terminal = H level, all outputs (OUT0~7) are off. An external resistor is connected between R-EXT and GND for setting up the value of constant current. SERIAL-OUT changes state on the rising edges of clock. Pin Description PIN No. PIN NAME FUNCTION 1 GND GND terminal 2 SERIAL-IN Input terminal of a data shift register 3 CLOCK Input terminal of a clock for shift register 4 LATCH Input terminal for data strobe 5~12 OUT0~7 Output terminals 13 ENABLE Input terminal for output enable (active low) 14 SERIAL-OUT Output terminal of a data shift register 15 R-EXT Input terminal of an external resistor 16 VDD 3.3/5V Supply voltage terminal OUT7 SERIAL-OUT OUT2 OUT1 OUT0 LATCH 0V 3.3/5V 0V 3.3/5V SERIAL IN CLOCK 0V 3.3/5V Off 0V Off On Off On Off 0V 3.3/5V 3.3/5V ENABLE |
