The maximum frequency of operation for the CD74HC373E is 25 MHz.
Yes, the CD74HC373E is compatible with 5V systems, but it can also operate at lower voltages down to 2V.
To ensure that the outputs are in a high-impedance state during power-up, you can use an external pull-up or pull-down resistor on the OE (Output Enable) pin.
The propagation delay time for the CD74HC373E is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
Yes, the CD74HC373E can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for better performance and reliability.
