The STP24DP05 is a monolithic, low-voltage, low-current power 24-bit shift register designed for LED panel displays. It contains an 8x3-bit serial-IN, parallel-OUT shift register that feeds an 8x3-bit D-type storage register. The output stage includes twenty-four regulated current sources providing 5-80 mA constant current to drive LEDs.
