STP08CDC596 8-BIT CONSTANT CURRENT LED SINK DRIVER WITH FULL OUTPUT DETECTION ■ ■ ■ ■ ■ ■ ■ 8 CONSTANT CURRENT OUTPUT CHANNELS ADJUSTABLE OUTPUT CURRENT THROUGH ONE EXTERNAL RESISTOR OPEN AND SHORT LINE, SHORT TO GND, SHORT TO V-LED SUPPLY ERROR DETECTION SERIAL DATA IN/PARALLEL DATA OUT SERIAL OUT CHANGE STATE ON THE FALLING EDGES OF CLOCK OUTPUT CURRENT: 20-120 mA 25 MHz CLOCK FREQ. DIP-16 SO-16 DESCRIPTION The STP08CDC596 is a monolithic, medium-voltage, low current power 8-bit shift register designed for LED panel display. The STP08CDC596 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. The STP08CDC596 contains the built-IN error detection feature. The device performs this additional function without any increase of the pin number and any change of the pin function, if compared to the standard device without error detection. Consequently, choosing this device does not mean to change the footprint on the board. To perform this functionality mode, the device needs a digital key coming from the Microprocessor. The STP08CDC596 is able to detect: open and short on the LED line, short to Table 1: Order Codes Type STP08CDC596B1 STP08CDC596M STP08CDC596MTR STP08CDC596TTR Temp.
