CD54ACT373F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54ACT373F3A?
  The recommended operating voltage range for CD54ACT373F3A 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 CD54ACT373F3A in high-speed applications?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors at the receiving end. Also, consider using a series resistor at the output of the CD54ACT373F3A to reduce ringing and overshoot.
• Can I use CD54ACT373F3A in a 3.3V system?
  Yes, CD54ACT373F3A can operate at 3.3V, but the output voltage will be reduced, and the device may not meet the specified propagation delay and transition times. However, it will still function correctly, and the output voltage will be sufficient to drive most 3.3V logic circuits.
• How do I handle power sequencing when using CD54ACT373F3A 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. Also, consider using a power sequencing controller or a voltage supervisor to ensure proper power-up and power-down sequencing.
• What is the maximum frequency of operation for CD54ACT373F3A?
  The maximum frequency of operation for CD54ACT373F3A is typically around 100 MHz, although it can operate at higher frequencies with reduced performance. The actual frequency limit will depend on the specific application, PCB design, and signal integrity.
