The maximum clock frequency of the SN74LV573ARGYR is 100 MHz.
To ensure that the output is not corrupted during power-up or power-down, it is recommended to use an external pull-up or pull-down resistor on the output pins, and to use a power-on reset circuit to initialize the device.
Yes, the SN74LV573ARGYR is compatible with 3.3V systems. It has a wide operating voltage range of 2.5V to 3.6V, making it suitable for use in 3.3V systems.
The asynchronous reset input (CLR) should be tied to a logic high level when not in use. When the CLR input is low, the device is reset, and all outputs are set to a logic low level.
The SN74LV573ARGYR can drive a maximum capacitive load of 100 pF.
