The recommended operating voltage range for the 74HC74DB,118 is 2V to 6V, with a typical voltage of 5V.
To ensure reliable operation of the flip-flop, make sure to meet the setup and hold time requirements, and avoid clock skew or jitter. Also, ensure that the input signals are clean and free of noise.
Yes, the 74HC74DB,118 can be used in a 3.3V system, but the output voltage will be limited to around 3.2V due to the internal voltage drop. This may affect the noise margin and signal integrity.
The asynchronous reset input (R) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the flip-flop is properly reset. Avoid leaving the R input floating or unconnected.
The maximum clock frequency that the 74HC74DB,118 can handle is around 100 MHz, but this may vary depending on the specific application, operating voltage, and temperature.
