74ACT138SCX Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 74ACT138SCX is 4.5V to 5.5V.
  • To ensure proper powering, connect VCC to a stable 5V power supply, and GND to a reliable ground connection. Also, decouple the power supply with a 0.1uF capacitor.
  • The maximum frequency of operation for the 74ACT138SCX is 100 MHz.
  • The enable inputs (E1, E2, E3) are active-low, so connect them to GND to enable the corresponding output. Connect them to VCC to disable the output.
  • The propagation delay for the 74ACT138SCX is typically 10ns, but it can vary depending on the operating conditions and load capacitance.
