Overview
The STP16CP05 is a monolithic, low-voltage, low-current power 16-bit shift register designed specifically for LED panel displays. It contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit, D-type storage register. The output stage features sixteen regulated current sources that provide constant current from 5 mA to 100 mA to drive LEDs. The device is capable of driving LEDs with a high clock frequency of 30 MHz, making it suitable for high data rate transmission. It operates with a 3.3 V voltage supply, which is convenient for applications interfacing with 3.3 V microcontrollers. The STP16CP05 also allows for the adjustment of LED brightness using an external resistor and guarantees a 20 V output driving capability, enabling the connection of more LEDs in series.
