MM74HC138N Frequently Asked Questions (FAQs)

  • The MM74HC138N can operate up to 25 MHz, but this frequency may vary depending on the specific application and operating conditions.
  • The MM74HC138N requires a single 2V to 6V power supply, and it's essential to decouple the power supply with a 0.1uF capacitor to minimize noise and ensure stable operation.
  • The MM74HC138N can sink up to 25mA and source up to 20mA per output, but it's recommended to limit the current to 10mA per output to ensure reliable operation.
  • The enable inputs (E1, E2, E3) must be connected to a valid logic level (either VCC or GND) to enable or disable the decoder. Leaving these inputs floating can cause unpredictable behavior.
  • The propagation delay of the MM74HC138N is typically around 10ns to 20ns, depending on the operating conditions and output load.
