CD74AC138M Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74AC138M is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper power supply, connect VCC to a 5V power source and GND to a reliable ground. Also, ensure that the power supply is decoupled with a 0.1uF capacitor to reduce noise and voltage spikes.
  • The CD74AC138M can sink or source up to 24mA of current per output, but it's recommended to limit the current to 16mA to ensure reliable operation.
  • The enable inputs (E1, E2, E3) are active-low, meaning they must be pulled low to enable the corresponding output. Connect unused enable inputs to VCC or GND to prevent floating inputs.
  • The propagation delay of the CD74AC138M is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
