The SN74HCT573PW can handle clock frequencies up to 30 MHz.
To ensure that the output is in a high-impedance state during power-up, connect the OE (output enable) pin to VCC through a pull-up resistor.
The SN74HCT573PW can sink or source up to 6 mA of current per output pin.
Yes, the SN74HCT573PW is compatible with 5V systems, but it is recommended to use a voltage regulator to ensure a stable 5V supply.
The asynchronous reset (R) input should be tied to VCC through a pull-up resistor to prevent unwanted resets. A capacitor can also be added to filter out noise.
