CD54HCT04F datasheet by Texas Instruments

CD54HCT04F Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD54HCT04F?
  The maximum frequency of operation for the CD54HCT04F is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD54HCT04F is properly powered?
  To ensure proper power supply, connect VCC to a 4.5V to 5.5V power source, and GND to a reliable ground. Also, make sure to decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the input voltage threshold for the CD54HCT04F?
  The input voltage threshold for the CD54HCT04F is typically around 1.5V to 3.5V, but it can vary depending on the specific application and operating conditions. It's recommended to consult the datasheet for more information.
• Can I use the CD54HCT04F in a 3.3V system?
  Yes, the CD54HCT04F can be used in a 3.3V system, but it's essential to ensure that the input voltage threshold is met, and the output voltage is within the specified range. Additionally, consult the datasheet for any specific recommendations or limitations.
• How do I handle unused inputs on the CD54HCT04F?
  Unused inputs on the CD54HCT04F should be tied to VCC or GND through a 1kΩ to 10kΩ resistor to prevent floating inputs and ensure proper operation.
