74HCT164D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HCT164D?
  The maximum clock frequency for the 74HCT164D is 30 MHz, but it can be limited by the system's noise margin and the quality of the clock signal.
• How do I ensure that the 74HCT164D is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply with a minimum of 10uF decoupling capacitor between VCC and GND, and place the capacitor as close to the device as possible.
• What is the maximum current that can be sourced or sunk by the 74HCT164D's outputs?
  The 74HCT164D's outputs can source or sink up to 6mA, but it's recommended to limit the current to 4mA to ensure reliable operation.
• Can I use the 74HCT164D with a 3.3V power supply?
  No, the 74HCT164D is designed to operate with a 5V power supply. Using a 3.3V power supply may result in unreliable operation or damage to the device.
• How do I handle the asynchronous reset input (RST) during power-up?
  To ensure proper reset, tie the RST input to VCC through a 1kΩ resistor and add a 10nF capacitor between RST and GND to filter out noise.
