The STP08CDC596 is a monolithic, mediumvoltage, low current power 8-bit shift register designed for LED panel display. The STP08CDC596 contains a 8-bit serial-in, parallelout shift register that feeds a 8-bitD-type storage register. In the output stage, eight regulated current sources were designed to provide 15- 120mA constant current to drive the LEDs.
■ 8 constant current output channels
■ Adjustable output current through one external resistor
■ Open and short line, short to GND, short to V-LED supply error detection
■ Serial data in/parallel data out
■ Serial out change state on the falling edges of clock
■ Output current: 20-120mA
■ 3.3V micro driver-able
■ 25MHz clock frequency
■ Available in high thermal TSSOP exposed pad.
