The maximum frequency of operation for the SN74AHC14N is 100 MHz.
Yes, the SN74AHC14N is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
The SN74AHC14N has a thermal pad on the bottom of the package, which should be connected to a heat sink or a thermal pad on the PCB to ensure proper heat dissipation.
The recommended termination for the SN74AHC14N is a 50-ohm series resistor at the output of each inverter, and a 50-ohm parallel resistor at the input of each inverter.
Yes, the SN74AHC14N is suitable for high-reliability applications, but it's recommended to follow proper design and manufacturing guidelines to ensure the device operates within its specified parameters.
