STP08DP05XTTR

The STP08DP05XTTR is a 8-bit low-voltage constant current LED Sink with full outputs error detection. The monolithic low voltage/low current shift register designed for LED panel displays. 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 5 to 100mA constant current to drive the LEDs. The STP08DP05 is backward compatible in the functionality and footprint with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to VO or open line. The data detection results are loaded in the shift register and shifted out via the serial line output.

• Adjustable output current through external resistor
• Short and open output error detection
• Serial data-in/parallel data-out
• 3.3V Micro driver-able
• 2.5kV HBM and 200V MM ESD protection
