SNJ54HC21J Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the SNJ54HC21J is 2V to 6V, with a typical voltage of 5V.
  • The input voltage thresholds for the SNJ54HC21J are typically 0.5V to 1.5V for a low input and 3.5V to 5V for a high input. It's recommended to use a voltage divider or a level shifter to ensure the input voltage is within the recommended range.
  • The maximum clock frequency that the SNJ54HC21J can handle is 25 MHz, but it's recommended to operate at a frequency of 10 MHz or less to ensure reliable operation.
  • It's recommended to use a 0.1uF ceramic capacitor between the VCC pin and GND pin, and a 10uF electrolytic capacitor between the VCC pin and GND pin to ensure proper power decoupling and noise reduction.
  • The typical propagation delay for the SNJ54HC21J is around 10ns to 20ns, depending on the operating voltage and temperature.
