SN74AHC74DBR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74AHC74DBR is 100 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a valid logic level (either VCC or GND) through a pull-up or pull-down resistor. This will ensure that the flip-flops are initialized to a known state on power-up.
  • The recommended operating voltage range for the SN74AHC74DBR is 2.0 V to 5.5 V, with a typical operating voltage of 3.3 V or 5 V.
  • The asynchronous preset and clear inputs (PRE and CLR) should be synchronized with the clock signal to avoid metastability issues. This can be done by using a synchronizer circuit or by ensuring that the preset and clear inputs are stable before the clock signal is applied.
  • The maximum propagation delay time for the SN74AHC74DBR is approximately 10 ns, but this can vary depending on the operating conditions and the load capacitance.
