M74HC165M1R Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the M74HC165M1R?
  The maximum clock frequency for the M74HC165M1R is 25 MHz.
• Can I use the M74HC165M1R with a 5V power supply?
  No, the M74HC165M1R is designed to operate with a power supply voltage of 2.0V to 3.6V. Using a 5V power supply may damage the device.
• How do I reset the shift register?
  The M74HC165M1R has a asynchronous reset input (RST) that can be used to reset the shift register. When the RST input is low, the shift register is reset and all outputs are set to low.
• What is the propagation delay time for the M74HC165M1R?
  The propagation delay time for the M74HC165M1R is typically 10ns (max) for the clock-to-output delay and 15ns (max) for the data-to-output delay.
• Can I use the M74HC165M1R in a 3.3V system?
  Yes, the M74HC165M1R is compatible with 3.3V systems. The device is designed to operate with a power supply voltage of 2.0V to 3.6V, making it suitable for use in 3.3V systems.
