SN74F138DR Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74F138DR is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF ceramic capacitor between VCC and GND, and use a 10uF electrolytic capacitor between VCC and GND for bulk decoupling.
  • The SN74F138DR can sink or source up to 24mA of current per output, but it's recommended to limit the current to 16mA per output to ensure reliable operation.
  • The enable inputs (E1, E2, E3) are active-low, so they should be pulled low to enable the corresponding output. Use a pull-up resistor to ensure the enable inputs are high when not in use.
  • The propagation delay of the SN74F138DR is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
