SN74LVC74ADBR datasheet by Texas Instruments

SN74LVC74ADBR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LVC74ADBR can handle?
  The maximum clock frequency of the SN74LVC74ADBR is 150 MHz.
• How do I ensure that the flip-flops are properly initialized during power-up?
  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.
• What is the recommended operating voltage range for the SN74LVC74ADBR?
  The recommended operating voltage range for the SN74LVC74ADBR is 1.65 V to 3.6 V.
• Can I use the SN74LVC74ADBR in a 5V system?
  No, the SN74LVC74ADBR is not recommended for use in 5V systems. It is designed for low-voltage applications (1.65 V to 3.6 V).
• How do I handle the asynchronous preset (PRE) and clear (CLR) inputs?
  The preset (PRE) and clear (CLR) inputs are asynchronous, meaning they can be asserted at any time, including during clock transitions. Ensure that these inputs are synchronized with the clock signal to avoid metastability issues.
