SN74AC574DWR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74AC574DWR is 100 MHz.
  • To prevent output corruption during power-up, connect the OE (output enable) pin to GND or use a pull-down resistor to ensure that the outputs are in a high-impedance state until the power supply has stabilized.
  • The MR pin is an asynchronous reset input that resets all flip-flops when it is low. It is used to reset the device to a known state.
  • Yes, the SN74AC574DWR is compatible with 3.3V systems. However, ensure that the input signals are 3.3V-compatible and that the output loads are within the recommended specifications.
  • To minimize power consumption, use the lowest possible clock frequency, minimize the number of transitions on the clock and data inputs, and consider using a lower-power alternative device if possible.
