SN74HC164PWR datasheet by Texas Instruments

SN74HC164PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the SN74HC164PWR?
  The maximum clock frequency for the SN74HC164PWR is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.
• How do I ensure that the shift register is properly reset after power-on?
  To ensure proper reset, connect the MR (Master Reset) pin to a power-on reset circuit or a manual reset button. This will ensure that the shift register is reset to a known state after power-on or manual reset.
• What is the maximum capacitance that can be driven by the SN74HC164PWR outputs?
  The maximum capacitance that can be driven by the SN74HC164PWR outputs is 100 pF. Exceeding this limit may cause signal degradation or oscillations.
• Can I use the SN74HC164PWR as a serial-to-parallel converter?
  Yes, the SN74HC164PWR can be used as a serial-to-parallel converter. Simply clock in the serial data and then latch the output to obtain the parallel data.
• How do I handle the asynchronous reset signal (MR) during power-on?
  During power-on, the MR pin should be held low for a minimum of 10 ns to ensure proper reset. This can be achieved using a power-on reset circuit or a manual reset button.
