The maximum operating frequency of the SN74HC7001DR is 100 MHz.
Yes, the SN74HC7001DR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
It's recommended to power up the VCC pin first, followed by the input signals, and power down the input signals first, followed by the VCC pin.
The recommended termination scheme is to use a 50-ohm resistor in series with the output pin and a 50-ohm resistor to ground.
The SN74HC7001DR is rated for operation up to 85°C, but it's recommended to derate the device for temperatures above 70°C to ensure reliable operation.
