Overview
The STP08DP05MTR, produced by STMicroelectronics, is a monolithic, low-voltage, low-current power 8-bit shift register designed specifically for LED panel displays. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The output stage features eight regulated current sources that provide a constant current of 5-100 mA to drive LEDs. The STP08DP05MTR is backward compatible with the STP8C/L596 and extends its functionality with the addition of open and short detection on the outputs.
