The recommended operating voltage range for the SN74HCT14DTG4 is 4.5V to 5.5V, 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 oscillations.
The maximum frequency of operation for the SN74HCT14DTG4 is typically around 30MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper decoupling, a 0.1uF ceramic capacitor should be placed as close as possible to the VCC pin, and a 10uF electrolytic capacitor should be placed near the device to filter out any noise or ripple on the power supply.
The maximum output current that the SN74HCT14DTG4 can sink or source is typically around 20mA, but this can vary depending on the specific application and operating conditions.
