SN74AHCT138PW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74AHCT138PW is 100 MHz.
  • Ensure that the VCC pin is connected to a stable 5V power supply, and the GND pin is connected to a reliable ground. Also, decouple the power supply with a 0.1uF capacitor to reduce noise.
  • The SN74AHCT138PW can sink or source up to 24mA of current per output pin.
  • The enable inputs (E1, E2, E3) are active-low, meaning they must be pulled low to enable the decoder. Connect unused enable inputs to VCC or GND as required.
  • The propagation delay of the SN74AHCT138PW is typically around 10ns, but can vary depending on the operating conditions and load capacitance.
