The maximum clock frequency of the SN74F74DR is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
To ensure proper reset during power-up, connect the preset (PRE) and clear (CLR) inputs to VCC through a 1 kΩ resistor and a 0.1 μF capacitor to ground. This will ensure that the flip-flop is properly reset during power-up.
The recommended operating voltage range for the SN74F74DR is 4.5 V to 5.5 V, with a typical operating voltage of 5 V.
To minimize power consumption, use a low-power mode of operation, reduce the clock frequency, and minimize the number of transitions on the clock input. Additionally, consider using a low-power version of the SN74F74DR, such as the SN74LV74.
The maximum input voltage that the SN74F74DR can tolerate is 7 V, but it is recommended to keep the input voltage below 5.5 V to ensure reliable operation.
