The maximum frequency of operation for the CD74HCT11E is 30 MHz.
Yes, the CD74HCT11E can operate with a 5V power supply, but it is recommended to use a 3.3V or lower power supply for optimal performance.
To ensure proper termination, connect a 50-ohm resistor between the output of the CD74HCT11E and the load, and a 50-ohm resistor between the output and ground.
The CD74HCT11E can sink or source up to 6 mA of current per output.
The CD74HCT11E is rated for operation up to 85°C, but it is recommended to derate the device for operation above 70°C to ensure reliability.
