CD74HC112E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC112E?
  The maximum frequency of operation for the CD74HC112E is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC112E is properly powered?
  To ensure proper power supply, connect VCC to a stable 2-V to 6-V power source, and GND to a reliable ground connection. 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 CD74HC112E can handle?
  The maximum input voltage that the CD74HC112E can handle is 6.5 V, which is the absolute maximum rating. However, it's recommended to keep the input voltage within the recommended operating range of 2 V to 6 V for reliable operation.
• How do I handle unused inputs on the CD74HC112E?
  Unused inputs on the CD74HC112E should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unpredictable behavior. This helps to ensure reliable operation and reduces power consumption.
• Is the CD74HC112E compatible with 3.3-V and 5-V logic systems?
  Yes, the CD74HC112E is compatible with both 3.3-V and 5-V logic systems, making it a versatile component for a wide range of applications.
