DESCRIPTION

The STP8CL596 is a monolithic, medium-voltage, low current power 8-bit shift register designed for LED panel display. The STP8CL596 contains a 8-bit serial-in, parallel-out shift register that feeds a 8-bitD-type storage register. In the output stage, sixteen regulated current sources were designed to provide 15-90mA constant current to drive the LEDs. Compared with the STPIC6C595, the device provides great flexibility and improved performance in LED panel system design. Trough an external resistor, users may adjust the STP8CL596 output current, controlling in this way the light intensity of LEDs. The STP8CL596 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. The 3.3V of voltage supply is well useful for applications that interface any micro from 3.3V to 5.5V. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor. Table 1: Order Codes Part Number Temp.
