DESCRIPTION The STP08C596 is a monolithic, medium-voltage, low current power 8-bit shift register designed for LED panel display. The STP08C596 contains a 8-bit serial-in, parallel-out shift register that feeds a 8-bitD-type storage register. In the output stage, eight regulated current sources were designed to provide 15-120mA constant current to drive the LEDs. Compared with the STPIC6C595, the device provides great flexibility and improved performance in LED panel system design. Table 1: Order Codes

Trough an external resistor, users may adjust the STP08C596 output current, controlling in this way the light intensity of LEDs. The STP08C596 guarantees 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 25 MHz, also satisfies the system requirement of high volume data transmission.
