CD74AC273E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74AC273E?
  The maximum frequency of operation for the CD74AC273E is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74AC273E is properly powered?
  To ensure proper power supply, connect VCC to a 5V power source and GND to a common ground. Make sure to decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the maximum current that the CD74AC273E can sink or source?
  The CD74AC273E can sink or source up to 24mA of current per output, but it's recommended to limit the current to 16mA to ensure reliable operation.
• How do I handle the propagation delay of the CD74AC273E?
  The propagation delay of the CD74AC273E is typically around 10ns, but it can vary depending on the operating conditions. To handle the delay, ensure that the input signals are properly synchronized and consider using a clock signal with a sufficient setup and hold time.
• Is the CD74AC273E compatible with 3.3V logic?
  The CD74AC273E is a 5V device, but it can be used with 3.3V logic with proper level shifting. Use a level translator or a voltage divider to ensure that the input signals are compatible with the 5V supply voltage.
