The maximum frequency of operation for the SN74HC7001D is 100 MHz.
Yes, the SN74HC7001D 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 then the output enable (OE) pin. During power-down, reverse the sequence.
The SN74HC7001D can sink or source up to 25 mA of current per output pin.
The SN74HC7001D 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.
