Overview
The STP16CP05MTR is a monolithic, low-voltage, low-current power 16-bit shift register designed specifically for LED panel displays. It is part of the STP16CP05 series from STMicroelectronics. This device 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, providing constant current from 5 mA to 100 mA to drive LEDs. The device supports a high clock frequency of 30 MHz, making it suitable for high data rate transmission, and it can be driven by a 3.3 V microcontroller. The STP16CP05MTR also offers adjustable output current through an external resistor and guarantees a 20 V output driving capability, allowing for more LEDs to be connected in series.
