SN74ALS164AN datasheet by Texas Instruments

SN74ALS164AN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74ALS164AN can handle?
  The maximum clock frequency of the SN74ALS164AN is 40 MHz, but it can vary depending on the operating voltage and load capacitance. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.
• How do I ensure that the SN74ALS164AN is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 5V power supply, and decouple the power pins with 0.1uF ceramic capacitors to ground. Additionally, use a 10uF electrolytic capacitor to filter the power supply.
• What is the maximum input voltage that the SN74ALS164AN can tolerate?
  The maximum input voltage that the SN74ALS164AN 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.
• Can I use the SN74ALS164AN in a 3.3V system?
  No, the SN74ALS164AN is not designed to operate at 3.3V. It's a 5V device, and operating it at 3.3V may result in unreliable operation or damage to the device.
• How do I handle the asynchronous reset input (CLR) during power-up?
  During power-up, the CLR input should be held low for at least 10ns to ensure that the device is properly reset. After power-up, the CLR input can be released, and the device will start operating normally.
