SN74LVTH574DWR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LVTH574DWR is 100 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND, depending on the desired initial state, and hold them in that state until the power supply has stabilized.
  • Texas Instruments recommends using a 22-ohm to 33-ohm series resistor in conjunction with a 10-pF to 22-pF capacitive load to minimize ringing and ensure signal integrity.
  • Yes, the SN74LVTH574DWR is compatible with 3.3V systems, but ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V) to maintain proper operation.
  • The preset and clear inputs are asynchronous, meaning they can be asserted at any time, including during clock transitions. However, to avoid potential metastability issues, it is recommended to synchronize these inputs to the clock signal or use them only during initialization or reset sequences.
