SN74HC163PWR datasheet by Texas Instruments

SN74HC163PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC163PWR can handle?
  The maximum clock frequency of the SN74HC163PWR is 30 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 SN74HC163PWR is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 2-6V power supply, and decouple the power pins with 0.1uF ceramic capacitors. Additionally, use a 10uF bulk capacitor to filter out noise and voltage drops.
• What is the maximum input voltage that the SN74HC163PWR can tolerate?
  The maximum input voltage that the SN74HC163PWR can tolerate is 7V, but it's recommended to keep the input voltage within the recommended operating range of 2-6V to ensure reliable operation.
• How do I handle the asynchronous reset input (RST) in my design?
  The asynchronous reset input (RST) should be tied to a logic high (VCC) during normal operation. When the RST input is pulled low, the counter resets to zero. Ensure that the RST input is properly debounced and synchronized with the clock signal to avoid metastability issues.
• What is the recommended clock signal rise and fall time for the SN74HC163PWR?
  The recommended clock signal rise and fall time for the SN74HC163PWR is 10ns or less to ensure reliable operation. Slower rise and fall times may cause the counter to malfunction or exhibit metastability.
