SN54HC138J Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN54HC138J is 40 MHz.
  • Ensure that the SN54HC138J is powered with a stable 5V supply, and that the power supply noise is minimized to prevent errors.
  • The SN54HC138J can sink or source up to 6 mA of current per output pin.
  • The enable inputs (E1, E2, E3) must be tied to a valid logic level (either VCC or GND) to ensure proper operation. Floating the enable inputs can cause unpredictable behavior.
  • The propagation delay of the SN54HC138J is typically around 10-15 ns, but can vary depending on the operating conditions and load capacitance.
