The maximum operating frequency of the 74AHC574PW,118 is 100 MHz.
Yes, the 74AHC574PW,118 is 5V tolerant, meaning it can accept input voltages up to 5.5V even when operating at a lower VCC voltage.
The power consumption of the 74AHC574PW,118 depends on the operating frequency and voltage. At 3.3V and 100 MHz, the typical power consumption is around 15mA.
Yes, the 74AHC574PW,118 can be used in a 3.3V system with 5V inputs, but you need to ensure that the input voltage does not exceed 5.5V and that the input current does not exceed the maximum rating.
The propagation delay of the 74AHC574PW,118 is typically around 3.5ns at 3.3V and 25°C.
