CD74HC74M96 datasheet by Texas Instruments

CD74HC74M96 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC74M96 can handle?
  The maximum clock frequency of the CD74HC74M96 is typically 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the flip-flops are properly initialized on power-up?
  To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a logic high level during power-up. This will set the flip-flops to a known state.
• What is the recommended operating voltage range for the CD74HC74M96?
  The recommended operating voltage range for the CD74HC74M96 is 2.0 V to 6.0 V, with a typical operating voltage of 5.0 V.
• Can I use the CD74HC74M96 in a 3.3 V system?
  Yes, the CD74HC74M96 can operate at 3.3 V, but the maximum clock frequency may be reduced at lower voltage levels.
• How do I handle the asynchronous preset (PRE) and clear (CLR) inputs?
  The preset and clear inputs are asynchronous, meaning they can be asserted at any time, regardless of the clock signal. However, it's recommended to synchronize these inputs with the clock signal to avoid metastability issues.
