CD74HC04E datasheet by Texas Instruments

CD74HC04E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC04E?
  The maximum frequency of operation for the CD74HC04E is typically 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC04E is properly powered?
  To ensure proper power supply, connect VCC to a stable 2-6V power source, and GND to a reliable ground connection. Also, decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the input voltage threshold for the CD74HC04E?
  The input voltage threshold for the CD74HC04E is typically around 1.5V for a logic high and 0.5V for a logic low, but it can vary depending on the specific application and operating conditions.
• Can I use the CD74HC04E in a 3.3V system?
  Yes, the CD74HC04E can be used in a 3.3V system, but ensure that the input signals are within the recommended voltage range (2-6V) and that the output is not loaded excessively.
• How do I handle unused inputs on the CD74HC04E?
  Unused inputs on the CD74HC04E should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
