The recommended operating voltage range for the SNJ54HC00W is 2V to 6V, with a typical voltage of 5V.
When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unwanted behavior.
The maximum frequency of operation for the SNJ54HC00W is 25 MHz at 5V and 10 MHz at 3.3V.
To ensure that the output signals are not distorted or attenuated, it is recommended to use a pull-up resistor of 1 kΩ to 10 kΩ on the output pins, and to keep the output load capacitance below 50 pF.
Yes, the SNJ54HC00W can be used in a 3.3V system, but the maximum frequency of operation will be reduced to 10 MHz.
