74HC74DB,118 datasheet by NXP Semiconductors

74HC74DB,118 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74HC74DB,118?
  The recommended operating voltage range for the 74HC74DB,118 is 2V to 6V, with a typical voltage of 5V.
• How do I ensure reliable operation of the flip-flop in the 74HC74DB,118?
  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.
• Can I use the 74HC74DB,118 in a 3.3V system?
  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.
• How do I handle the asynchronous reset input (R) in the 74HC74DB,118?
  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.
• What is the maximum clock frequency that the 74HC74DB,118 can handle?
  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.
