CD74HC32E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC32E?
  The maximum frequency of operation for the CD74HC32E is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC32E is properly powered?
  To ensure proper operation, the CD74HC32E should be powered with a stable voltage supply between 2.0V and 6.0V, with a recommended operating voltage of 5.0V. Additionally, decoupling capacitors should be used to filter out noise and ensure stable operation.
• What is the propagation delay of the CD74HC32E?
  The propagation delay of the CD74HC32E is typically around 10-15 ns, but this can vary depending on the specific operating conditions and temperature.
• Can I use the CD74HC32E in a 3.3V system?
  Yes, the CD74HC32E can be used in a 3.3V system, but the output voltage will be limited to around 3.3V. Additionally, the input voltage thresholds may be affected, and the device may not operate at the same speed as it would at 5.0V.
• How do I handle unused inputs on the CD74HC32E?
  Unused inputs on the CD74HC32E should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
