The recommended operating voltage range for the SN74HCS04QPWRQ1 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 behavior.
The maximum frequency of operation for the SN74HCS04QPWRQ1 is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.
To ensure that the output signals are not distorted or attenuated, it is recommended to use a suitable load impedance and to keep the output traces as short as possible to minimize signal degradation.
The SN74HCS04QPWRQ1 is designed to operate at 5V, but it can be used with 3.3V logic levels with some limitations. The output voltage levels may not be fully compatible with 3.3V logic, and the device may not meet the required noise margins.
