SN74F86D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74F86D?
  The maximum frequency of operation for the SN74F86D is typically around 100 MHz, but it can vary depending on the specific application, supply voltage, and output load.
• How do I ensure that the SN74F86D operates within the recommended operating conditions?
  To ensure that the SN74F86D operates within the recommended operating conditions, make sure to operate it within the specified voltage range (4.5V to 5.5V), keep the junction temperature below 150°C, and avoid exceeding the maximum current ratings.
• What is the propagation delay of the SN74F86D?
  The propagation delay of the SN74F86D is typically around 10-15 ns, but it can vary depending on the specific application, supply voltage, and output load.
• Can I use the SN74F86D in a 3.3V system?
  While the SN74F86D is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage swing may be reduced, and the device may not meet the specified propagation delay and rise/fall times.
• How do I handle the input and output pins of the SN74F86D during power-up and power-down?
  During power-up and power-down, it's recommended to keep the input pins at a valid logic level (either high or low) to prevent unwanted output transitions. Additionally, consider using pull-up or pull-down resistors on the input pins to ensure a valid logic level.
