CD74HCT138M Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for CD74HCT138M is 30 MHz.
  • Yes, CD74HCT138M is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
  • The enable inputs (E1, E2, E3) are active-low, meaning they must be pulled low to enable the corresponding output. Connect them to GND or a logic low signal to enable the output.
  • The propagation delay of CD74HCT138M is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
  • Yes, CD74HCT138M can be used as a level translator, but it's not recommended as it's primarily designed as a 3-to-8 line decoder/demultiplexer. For level translation, consider using a dedicated level translator IC.
