SN74HCS74DR Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the SN74HCS74DR is 25 MHz.

  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC through a 1-kΩ resistor and a 0.01-μF capacitor to ground, respectively.

  • The recommended operating voltage range for the SN74HCS74DR is 4.5 V to 5.5 V.

  • To reduce power consumption, use the lowest possible clock frequency, minimize input transitions, and use a lower supply voltage (e.g., 4.5 V) if possible.

  • Yes, the SN74HCS74DR can operate at 3.3 V, but the maximum clock frequency may be limited to 12.5 MHz.
