SN74HC74NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74NSR 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 SN74HC74NSR 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 the asynchronous set (S) and reset (R) inputs only when necessary. Ensure that asynchronous inputs are synchronized with the clock signal to prevent metastability.
  • The maximum current that the SN74HC74NSR can sink or source is 25 mA per output pin.
