Overview
The STP08CP05XTTR is a monolithic, low voltage, low current power 8-bit shift register designed by STMicroelectronics. It is specifically tailored for LED panel displays. This component features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, providing eight regulated current sources to drive LEDs with constant current. The device is backward compatible in functionality and footprint with the STP8C/L596 series.
