CD74AC86E datasheet by Texas Instruments

CD74AC86E Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD74AC86E?
  The recommended operating voltage range for the CD74AC86E is 2.0V to 6.0V, with a typical voltage of 5.0V.
• How do I handle the input voltage thresholds for the CD74AC86E?
  The input voltage thresholds for the CD74AC86E are typically 0.5V to 2.0V for a low input and 3.0V to 5.0V for a high input. It's recommended to use a voltage divider or a level shifter if the input signal is not within these ranges.
• What is the maximum frequency of operation for the CD74AC86E?
  The maximum frequency of operation for the CD74AC86E is typically 100 MHz, but it can vary depending on the operating voltage and load capacitance. It's recommended to check the datasheet for specific frequency vs. voltage and load capacitance curves.
• How do I ensure proper power sequencing for the CD74AC86E?
  It's recommended to power up the CD74AC86E in the following sequence: VCC, then inputs, and finally outputs. This ensures that the device is properly initialized and prevents any potential latch-up or damage.
• What is the recommended termination scheme for the CD74AC86E outputs?
  The recommended termination scheme for the CD74AC86E outputs is to use a 50-ohm resistor in series with the output pin, followed by a 50-ohm load resistor to ground. This helps to reduce ringing and improve signal integrity.
