CD74HC20E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC20E?
  The maximum frequency of operation for the CD74HC20E is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC20E is properly powered?
  To ensure proper power supply, connect VCC to a 2.0-V to 6.0-V power supply, and GND to the system ground. Also, decouple the power supply with a 0.1-μF capacitor to reduce noise and ensure stable operation.
• What is the maximum input voltage that the CD74HC20E can handle?
  The maximum input voltage that the CD74HC20E can handle is 6.0 V, which is the maximum rating for the device. Exceeding this voltage can cause damage to the device.
• How do I handle the output of the CD74HC20E when it is not in use?
  When the CD74HC20E is not in use, it is recommended to tie the output to a fixed logic level (either VCC or GND) to prevent unwanted oscillations and reduce power consumption.
• Is the CD74HC20E compatible with 3.3-V and 5-V logic systems?
  Yes, the CD74HC20E is compatible with both 3.3-V and 5-V logic systems, making it a versatile device for use in a wide range of applications.
