SN74HC138DE4 Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HC138DE4 is 40 MHz, but it can vary depending on the operating voltage and load capacitance.
  • To ensure proper power supply, connect VCC to a stable 2-V to 6-V power supply, and GND to a solid ground plane. Also, decouple the power supply with a 0.1-μF ceramic capacitor.
  • The SN74HC138DE4 can sink up to 6 mA and source up to 5.2 mA per output pin, but the total current should not exceed 50 mA.
  • Unused inputs should be tied to a valid logic level (VCC or GND) to prevent floating inputs, which can cause unpredictable behavior.
  • Yes, the SN74HC138DE4 is compatible with 5-V logic, but it can also operate at lower voltages (2-V to 4.5-V) with reduced speed and current drive.
