SN74ALS164AD datasheet by Texas Instruments

SN74ALS164AD Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74ALS164AD can handle?
  The maximum clock frequency of the SN74ALS164AD is 40 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN74ALS164AD is properly powered and decoupled?
  To ensure proper power and decoupling, use a high-quality power supply with a low output impedance, and decouple the VCC pin with a 0.1 μF ceramic capacitor to ground. Additionally, use a 10 μF electrolytic capacitor in parallel to filter out any noise or ripple.
• What is the maximum input voltage that the SN74ALS164AD can tolerate?
  The maximum input voltage that the SN74ALS164AD can tolerate is 7V, but it's recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V to ensure reliable operation.
• How do I handle the asynchronous reset input (RST) of the SN74ALS164AD?
  The asynchronous reset input (RST) should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure that the device is properly reset. When the RST input is low, the device is reset, and all outputs are set to a low state.
• What is the propagation delay of the SN74ALS164AD?
  The propagation delay of the SN74ALS164AD is typically around 10 ns to 15 ns, but it can vary depending on the operating conditions, temperature, and load capacitance.
