STP08CP05 is a low voltage, low current, power 8-bit shift register designed for LED panel displays. It features adjustable output current, adjustable brightness, high driving capability, and high clock frequency.
The STP08CP05 is a monolithic, low voltage, low current, power 8-bit shift register designed specifically for LED panel displays. It 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 providing 5-100 mA constant current to drive LEDs, with an output current setup time of 11 ns (typ). The device supports a 3.3 V micro driver and offers a high clock frequency of 30 MHz. It is backward compatible in functionality and footprint with the STP8C/L596 and includes ESD protection up to 2.5 kV HBM. Users can adjust the output current via an external resistor to control LED brightness from 0% to 100% using the OE pin, and the device guarantees a 20 V output driving capability.
