The STPO8CP05 is a monolithic, low voltage, low current, power 8-bit shift register designed 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 designed to provide 5-100mA constant current to drive LEDs.
The device operates with a low voltage power supply down to 3V and supports a clock frequency of 30MHz. It is available in high thermal efficiency TSSOP packages with an exposed pad. The chip offers adjustable output current through an external resistor and allows brightness control from 0% to 100% via the OE pin.
