SN74HCT138NSR Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HCT138NSR is typically around 30-40 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper operation, the SN74HCT138NSR should be powered with a stable 5V supply, and decoupling capacitors (e.g. 0.1uF and 10uF) should be placed close to the device to filter out noise and reduce electromagnetic interference (EMI).
  • The SN74HCT138NSR can sink or source up to 6mA of current per output pin, but it's recommended to limit the current to 4mA or less to ensure reliable operation.
  • The enable inputs (E1, E2, E3) should be driven with a valid logic level (either high or low) to ensure proper operation. If an enable input is not used, it should be tied to a valid logic level to prevent unintended operation.
  • The propagation delay of the SN74HCT138NSR is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
