M74HCT04M1R Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HCT04M1R?
  The recommended operating voltage range for M74HCT04M1R is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle the input pins when they are not in use?
  When the input pins are not in use, they should be tied to VCC or GND through a resistor to prevent them from floating and causing unwanted oscillations.
• What is the maximum frequency of operation for M74HCT04M1R?
  The maximum frequency of operation for M74HCT04M1R is typically around 30MHz, but it can vary depending on the specific application and operating conditions.
• Can I use M74HCT04M1R in a 3.3V system?
  While M74HCT04M1R is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the noise margin may be reduced.
• How do I ensure that the output signals are not distorted or attenuated?
  To ensure that the output signals are not distorted or attenuated, it is recommended to use a pull-up or pull-down resistor on the output pins, and to keep the output traces short and well-terminated.
