SNJ54HC74J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SNJ54HC74J 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 SNJ54HC74J is 2V to 6V, with a typical operating voltage of 5V.
  • To handle asynchronous inputs, use synchronous inputs whenever possible, and use the asynchronous set (S) and reset (R) inputs only when necessary. Ensure that asynchronous inputs are synchronized with the clock signal.
  • The maximum propagation delay time for the SNJ54HC74J is 35 ns (typical) and 50 ns (maximum) at 25°C and 5V supply voltage.
