M74HC02TTR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HC02TTR?
  The recommended operating voltage range for M74HC02TTR is 2V to 6V, 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 floating inputs and reduce power consumption.
• What is the maximum frequency of operation for M74HC02TTR?
  The maximum frequency of operation for M74HC02TTR is 25 MHz at 5V and 10 MHz at 3.3V.
• How do I ensure that the output signals are not distorted?
  To ensure that the output signals are not distorted, it is recommended to use a pull-up or pull-down resistor on the output pins, and to keep the output load capacitance below 50 pF.
• Can I use M74HC02TTR in a 3.3V system?
  Yes, M74HC02TTR can be used in a 3.3V system, but the maximum frequency of operation will be limited to 10 MHz.
