SN74HCT138DT Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HCT138DT is 30 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 keep the power supply lines as short as possible.
  • The SN74HCT138DT can sink up to 6mA and source up to 6mA per output pin, but it's recommended to keep the current within 4mA to ensure reliable operation.
  • The enable inputs (E1, E2, E3) should be driven low to enable the decoder, and high to disable it. Use a pull-up or pull-down resistor to ensure a clear logic level.
  • The propagation delay of the SN74HCT138DT is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
