The maximum clock frequency for the SN74HC574PWRG4 is 35 MHz.
To ensure that the outputs are in a known state during power-up, connect the preset (PRE) input to VCC or GND, and the clear (CLR) input to VCC or GND, depending on the desired output state.
The recommended operating voltage range for the SN74HC574PWRG4 is 2 V to 6 V.
To handle asynchronous inputs, use synchronous inputs or add external synchronization circuits to ensure that the inputs are synchronized with the clock signal.
The maximum input current for the SN74HC574PWRG4 is ±20 mA.
