SN74LS164NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS164NSR is 36 MHz, but it can vary depending on the operating voltage and temperature.
  • To clear the shift register, you can pulse the CLEAR (CLR) input low while the clock (CLK) input is low. This will reset the internal flip-flops and clear the register.
  • The propagation delay time (tPD) for the SN74LS164NSR is typically around 20-30 ns, but it can vary depending on the operating voltage and temperature.
  • The SN74LS164NSR is a 5V device, but it can be used in a 3.3V system with some limitations. The device will still function, but the output voltage levels may not be compatible with 3.3V logic. You may need to use level translators or voltage dividers to interface with 3.3V devices.
  • The asynchronous clear input (CLR) should be handled carefully to avoid unintended clearing of the shift register. You can use a synchronous clear approach by clocking the CLR input with the clock (CLK) signal to ensure that the register is cleared only when intended.
