SNJ54HC161J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SNJ54HC161J is 25 MHz, but it can operate up to 40 MHz with a reduced voltage supply (VCC) of 4.5V.
  • To ensure proper power-on and initialization, the VCC pin should be ramped up slowly (typically 10 ms to 100 ms) to the recommended operating voltage, and the reset pin (MR) should be held low for at least 10 ns to initialize the counter.
  • The maximum input voltage that the SNJ54HC161J can tolerate on its input pins is 5.5V, which is higher than the recommended VCC voltage of 5V. However, it's recommended to keep the input voltage within the recommended operating range to ensure reliable operation.
  • Yes, the SNJ54HC161J can operate at a supply voltage (VCC) as low as 2V, making it suitable for use in 3.3V systems. However, the maximum clock frequency may be reduced at lower supply voltages.
  • The asynchronous reset (MR) input should be driven low for at least 10 ns to ensure proper reset of the counter. It's recommended to use a pull-up resistor on the MR pin to prevent unwanted resets.
