Overview
The STP08CP05 is a monolithic, low voltage, low current, power 8-bit shift register designed specifically for LED panel displays. This component, produced by STMicroelectronics, integrates an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The output stage includes eight regulated current sources, capable of providing a constant current of 5-100 mA to drive LEDs, with an output current setup time of 11 ns (typical), enhancing system performance. The STP08CP05 is backward compatible in functionality and footprint with the STP8C/L596 and allows for adjustable output current and brightness control through an external resistor and the OE pin.
