SN74AHC74DR Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the SN74AHC74DR is 100 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 prevent floating inputs.

  • The recommended operating voltage range for the SN74AHC74DR is 2.0 V to 5.5 V.

  • To minimize power consumption, use a low-frequency clock, minimize switching activity, and consider using a lower supply voltage (e.g., 3.3 V instead of 5 V).

  • Yes, the SN74AHC74DR is compatible with 3.3 V systems, but ensure that the input signals are within the recommended voltage range (0.8 V to 3.6 V).
