The maximum frequency of operation for the 74HC573D,653 is 100 MHz.
To ensure that the output is not corrupted during power-up or power-down, it is recommended to use a pull-up or pull-down resistor on the output pins to define the output state during power-up or power-down.
The recommended operating voltage range for the 74HC573D,653 is 2.0 V to 6.0 V.
During power-up or power-down, the asynchronous reset input (nRST) should be held low to ensure that the device is properly reset.
The maximum current that can be sourced or sunk by the output pins is 25 mA.
