Product overview

Description

The STP16CPC05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CPC05 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit, D-type storage register. In the output stage, sixteen regulated current sources provide from 5 mA to 100 mA constant current to drive the LEDs. The STP16CPC05`s output stage is designed to optimize the turn-on and turn-off time, typically 100 nS. The balanced turning ON/OFF improves the system performances reducing the bypass capacitance in applications where parasitic inductance generate ringing or noise in the system. The LEDs' brightness can be controlled by using an external resistor to adjust the STP16CPC05 output current. The STP16CPC05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, makes the device suitable for high data rate transmission. The 3.3 V voltage supply is useful in applications that interface with a 3.3 V microcontroller.
