SN74HC74DBR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74DBR is 25 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND, and use a pull-up or pull-down resistor to define the initial state.
  • The recommended operating voltage range for the SN74HC74DBR is 2 V to 6 V, with a typical operating voltage of 5 V.
  • To handle asynchronous inputs, use synchronous inputs whenever possible, and use asynchronous inputs only when necessary. Use a synchronizer circuit or a metastability resolver to handle asynchronous inputs.
  • The maximum current that the SN74HC74DBR can sink or source is 25 mA per output pin.
