STP08CDC596

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 GND, short to Led voltage supply. The data mapping of output channels status detection is provided by a feedback from the serial output to the Microprocessor.

Trough an external resistor, users may adjust the STP08CDC596 output current, controlling the light intensity of LEDs.

The STP08CDC596 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 device is offered in DIP-16, SO-16 and TSSOP-16 packages.

The STP08CDC596 is well suitable for traffic display signs where the detection feature is strongly required.
