74HCT08D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the 74HCT08D?
  The maximum frequency of operation for the 74HCT08D is typically around 30-40 MHz, but this can vary depending on the specific application, supply voltage, and output load.
• Can I use the 74HCT08D with a 5V supply voltage?
  Yes, the 74HCT08D is designed to operate with a supply voltage of 4.5V to 5.5V, making it compatible with 5V systems.
• What is the propagation delay of the 74HCT08D?
  The propagation delay of the 74HCT08D is typically around 10-15 ns, but this can vary depending on the specific application and operating conditions.
• Can I use the 74HCT08D in a 3.3V system?
  No, the 74HCT08D is not designed to operate with a supply voltage below 4.5V, so it is not suitable for use in 3.3V systems. You may need to consider a different device, such as the 74LVC08A, which is designed for low-voltage operation.
• What is the output current capability of the 74HCT08D?
  The output current capability of the 74HCT08D is typically around 20-25 mA per output, but this can vary depending on the specific application and operating conditions.
