The maximum frequency of operation for the CD74HCT640E is 50 MHz.
Yes, the CD74HCT640E is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. When OE is high, the outputs are in a high-impedance state.
The propagation delay of the CD74HCT640E is typically around 10 ns, but it can vary depending on the operating conditions and load capacitance.
No, the CD74HCT640E is not compatible with 3.3V systems. It's designed to operate at 4.5V to 5.5V supply voltage.
