The maximum frequency of operation for the CD74HC14M96 is 25 MHz.
Yes, the CD74HC14M96 is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
To prevent oscillation, ensure that the input signals have a fast rise and fall time (>10 ns) and use a pull-up or pull-down resistor to define the input state when the input signal is not present.
A simple power-on reset circuit can be implemented using a capacitor, resistor, and diode. The capacitor is charged through the resistor and diode, and the voltage across the capacitor is used to reset the device.
The CD74HC14M96 is rated for operation up to 125°C, but it's recommended to derate the device's performance and consider thermal management to ensure reliable operation in high-temperature environments.
