SNJ54HC191J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SNJ54HC191J is 25 MHz, but it can operate up to 40 MHz with a reduced voltage supply (VCC) of 4.5V.
  • To ensure proper operation, the SNJ54HC191J requires a stable power supply voltage (VCC) between 2V and 6V, with a recommended operating range of 4.5V to 5.5V. Additionally, decoupling capacitors should be used to filter out noise and ensure a clean power supply.
  • The maximum input voltage that the SNJ54HC191J can handle is 6V, but it is recommended to keep the input voltage within the recommended operating range of VCC + 0.5V to prevent damage to the device.
  • The SNJ54HC191J can be reset by applying a low logic level to the MR (Master Reset) input. The MR input should be held low for at least 10 ns to ensure a proper reset.
  • The propagation delay of the SNJ54HC191J is typically around 10 ns to 20 ns, depending on the operating frequency and voltage supply.
