SN74LS164DR datasheet by Texas Instruments

SN74LS164DR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the SN74LS164DR?
  The maximum clock frequency for the SN74LS164DR is 36 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the shift register is properly initialized on power-up?
  To ensure proper initialization, connect the CLR (clear) input to a power-on reset circuit or a manual reset switch to clear the register on power-up.
• Can I use the SN74LS164DR as a serial-to-parallel converter?
  Yes, the SN74LS164DR can be used as a serial-to-parallel converter by connecting the serial input to the data input and the clock input to a clock signal. The parallel output can be taken from the Q0-Q7 outputs.
• What is the maximum capacitance that can be driven by the SN74LS164DR outputs?
  The maximum capacitance that can be driven by the SN74LS164DR outputs is 100 pF, but this can vary depending on the specific application and operating conditions.
• How do I reduce power consumption in my design using the SN74LS164DR?
  To reduce power consumption, consider using a lower clock frequency, reducing the voltage supply, or using a power-down mode if available.
