CD74HC08M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC08M?
  The maximum frequency of operation for the CD74HC08M is typically around 25 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC08M is properly powered?
  The CD74HC08M requires a single power supply voltage (VCC) of 2.0 V to 6.0 V. Ensure that the power supply is stable and within the recommended operating range to ensure proper operation.
• What is the input voltage threshold for the CD74HC08M?
  The input voltage threshold for the CD74HC08M is typically around 0.8 V for a logic high and 0.2 V for a logic low, but this can vary depending on the specific application and operating conditions.
• Can I use the CD74HC08M in a 3.3 V or 5 V system?
  Yes, the CD74HC08M can be used in both 3.3 V and 5 V systems, as it is designed to operate over a wide range of power supply voltages.
• How do I handle unused inputs on the CD74HC08M?
  Unused inputs on the CD74HC08M should be tied to a logic high or low level to prevent floating inputs, which can cause unpredictable behavior.
