SN74AC574DW Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74AC574DW is 100 MHz.
  • To ensure proper initialization, connect the preset (PRE) input to VCC and the clear (CLR) input to GND. This will set the outputs to a known state on power-up.
  • The output enable (OE) input is used to enable or disable the outputs. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state.
  • Yes, the SN74AC574DW is compatible with 3.3V systems. However, ensure that the input signals are compatible with the device's input voltage levels.
  • The preset (PRE) and clear (CLR) inputs are asynchronous, meaning they can be asserted at any time, regardless of the clock signal. Ensure that these inputs are synchronized with the clock signal to avoid metastability issues.
