Description :

STP08C596 8-BIT CONSTANT CURRENT LED SINK DRIVER I I I I I I I I 8 CONSTANT CURRENT OUTPUT CHANNELS ADJUSTABLE OUTPUT CURRENT THROUGH EXTERNAL RESISTOR SERIAL DATA IN/PARALLEL DATA OUT SERIAL OUT CHANGE STATE ON THE FAILING EDGES OF CLOCK OUTPUT CURRENT: 15-120 mA 25 MHz CLOCK FREQ. AVAILABLE IN HIGH THERMAL TSSOP EXPOSED PAD EFFICIENCY PACKAGE DIP-16 SO-16 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, sixteen 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 Part Number STP08C596B1 STP08C596M STP08C596MTR STP08C596TTR Temp. Range -40°C to -40°C to -40°C to -40°C to 125°C 125°C 125°C 125°C TSSOP16 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.
