DESCRIPTION The STP16CL596 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CL596 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-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. Table 1: Order Codes

Trough an external resistor, users can adjust the STP16CL596 output current, controlling in this way the light intensity of LEDs. The STP16CL596 guarantees a 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 3.3……
