CD74HCT08M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HCT08M?
  The maximum frequency of operation for the CD74HCT08M is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HCT08M is properly powered?
  To ensure proper operation, the CD74HCT08M should be powered with a stable 5V supply, and decoupling capacitors should be used to filter out noise and voltage spikes.
• What is the input voltage threshold for the CD74HCT08M?
  The input voltage threshold for the CD74HCT08M is typically around 2.0V for a logic high and 0.8V for a logic low, but this can vary depending on the specific application and operating conditions.
• Can I use the CD74HCT08M with 3.3V logic?
  While the CD74HCT08M is designed for 5V operation, it can be used with 3.3V logic with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and additional level-shifting circuitry may be required.
• How do I handle unused inputs on the CD74HCT08M?
  Unused inputs on the CD74HCT08M should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
