The STP08CDC596 is a monolithic, medium-voltage, low current power 8-bit shift register designed for LED panel display. It contains a 8-bit serial-in, parallel-out shift register that feeds a 8-bit D-type storage register. In the output stage, eight regulated current sources were designed to provide 15-120mA constant current to drive the LEDs. The STP08CDC596 has built-in error detection feature, which can detect open and short on the LED line, short to GND, short to LED voltage supply. Users can adjust the output current of the STP08CDC596 through an external resistor to control the light intensity of LEDs.
The STP08CDC596 is a monolithic, medium-voltage, low-current power 8-bit shift register designed specifically for LED panel displays. It features a serial-in, parallel-out architecture that feeds an 8-bit D-type storage register to drive eight regulated current sources.

It detects an error if the detected output current (IODEC) is less than or equal to half of the programmed output current (IO).
A short is indicated if the output voltage (VO) rises to 2.4 V or higher.
