SN54LS164J datasheet by Texas Instruments

SN54LS164J Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS164J can handle?
  The maximum clock frequency of the SN54LS164J is 36 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN54LS164J is properly reset during power-up?
  To ensure proper reset, connect the CLR (clear) input to a pull-up resistor and a capacitor to VCC, and apply a reset pulse during power-up. This ensures that the shift register is cleared and ready for operation.
• What is the maximum capacitance that can be driven by the SN54LS164J?
  The SN54LS164J can drive a maximum capacitance of 100 pF, but it's recommended to keep the load capacitance as low as possible to ensure reliable operation.
• Can I use the SN54LS164J in a 3.3V system?
  The SN54LS164J is a 5V device, but it can be used in a 3.3V system with some limitations. However, the device's performance and reliability may be affected, and it's recommended to consult with Texas Instruments or a qualified engineer before doing so.
• How do I troubleshoot issues with the SN54LS164J?
  To troubleshoot issues with the SN54LS164J, check the power supply voltage, clock signal, and input signals. Use a logic analyzer or oscilloscope to verify the signal waveforms and timing. Also, ensure that the device is properly reset during power-up and that the inputs are properly terminated.
