SN74LVC74ADG4 datasheet by Texas Instruments

SN74LVC74ADG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74LVC74ADG4?
  The recommended operating voltage range for the SN74LVC74ADG4 is 1.65V to 3.6V.
• How do I ensure that the flip-flop is properly reset during power-up?
  To ensure proper reset during power-up, connect the reset pin (CLR) to VCC through a pull-up resistor (e.g., 1kΩ) and add a capacitor (e.g., 0.1μF) from the reset pin to GND to filter out any noise.
• What is the maximum clock frequency that the SN74LVC74ADG4 can handle?
  The maximum clock frequency that the SN74LVC74ADG4 can handle is 100 MHz.
• Can I use the SN74LVC74ADG4 in a 5V system?
  No, the SN74LVC74ADG4 is not recommended for use in 5V systems. It is designed to operate at a maximum voltage of 3.6V. Using it in a 5V system may cause damage to the device or affect its performance.
• How do I handle the asynchronous reset input (CLR) in my design?
  The asynchronous reset input (CLR) should be synchronized with the clock signal to avoid metastability issues. This can be done by using a flip-flop or a synchronizer circuit to synchronize the reset signal with the clock.
