The recommended operating voltage range for the CD74HC688NSR is 2V to 6V.
To ensure proper power supply, connect VCC to a stable voltage source, and GND to a reliable ground. Decouple the power supply with a 0.1uF capacitor to reduce noise.
The CD74HC688NSR can handle clock frequencies up to 25MHz.
The RST input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper reset functionality. A low-going pulse on RST resets the device.
The propagation delay time (tPD) for the CD74HC688NSR is typically around 15ns, but can vary depending on the operating voltage and temperature.
