SN74LS164D Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS164D is typically 25 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper initialization, it is recommended to reset the shift register by applying a low pulse to the CLR (clear) input before starting to clock in data.
  • There is no theoretical limit to the number of shift registers that can be cascaded, but it is limited by the loading of the clock and data lines, as well as the propagation delay of the signals.
  • When the shift register is not being clocked, the outputs will remain in their previous state. To avoid unwanted output transitions, it is recommended to use a three-state buffer or a latch to isolate the output.
  • The power consumption of the SN74LS164D depends on the operating frequency, voltage, and temperature. Typically, the quiescent current is around 15 mA, and the dynamic current is around 10 mA/MHz.
