CD54HCT390F3A datasheet by Texas Instruments

CD54HCT390F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54HCT390F3A?
  The recommended operating voltage range for CD54HCT390F3A is 4.5V to 5.5V.
• How do I ensure signal integrity when using CD54HCT390F3A in a high-speed application?
  To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors to minimize reflections.
• Can I use CD54HCT390F3A in a 3.3V system?
  While CD54HCT390F3A is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage swing will be reduced, and the device may not meet the specified propagation delay.
• How do I handle thermal considerations when using CD54HCT390F3A in a high-power application?
  To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and follow the recommended power dissipation guidelines in the datasheet.
• Are there any specific layout considerations I should be aware of when using CD54HCT390F3A?
  Yes, keep the input and output traces short and symmetrical, avoid crossing signal traces, and use a solid ground plane to minimize noise and crosstalk.
