CD74ACT297M Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74ACT297M?
  The recommended operating voltage range for the CD74ACT297M is 4.5V to 5.5V, although it can operate from 2V to 6V with reduced performance.
• How do I ensure signal integrity when using the CD74ACT297M in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors or series resistors to reduce reflections and ringing.
• Can I use the CD74ACT297M in a 3.3V system?
  Yes, the CD74ACT297M can operate at 3.3V, but the output voltage swing will be reduced, and the device may not meet the specified propagation delay and transition times.
• How do I handle power sequencing when using the CD74ACT297M in a system with multiple power supplies?
  To avoid latch-up or damage, ensure that the VCC supply is powered up before the input signals, and that the input signals are stable before the VCC supply is powered down.
• What is the maximum frequency of operation for the CD74ACT297M?
  The maximum frequency of operation for the CD74ACT297M is typically 100 MHz, but this can vary depending on the specific application and operating conditions.
