MC74HC147N Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the MC74HC147N is 25 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure valid outputs, make sure to connect the enable input (EI) to a valid logic level, and ensure that the clock input (CLK) is a clean, stable signal. Also, add a small capacitor (e.g., 10nF) between the VCC and GND pins to filter out noise.
  • Yes, the MC74HC147N is designed to operate with a 2V to 6V power supply, so 5V is within the recommended operating range.
  • The MC74HC147N is a priority encoder, which means it will encode the highest-priority input (i.e., the input with the highest binary value). If multiple inputs are active simultaneously, the encoder will output the code corresponding to the highest-priority input.
  • The propagation delay of the MC74HC147N is typically around 20-30 ns, but this can vary depending on the specific application and operating conditions.
