The recommended operating voltage range for the 74VHC138FT is 2.0V to 5.5V.
To ensure proper power supply, connect VCC to a stable voltage source and GND to a reliable ground. Decouple the power supply with a 0.1uF capacitor to reduce noise.
The maximum frequency of operation for the 74VHC138FT is 100 MHz.
The enable inputs (E1, E2, E3) must be connected to a valid logic level (VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
The maximum current that the 74VHC138FT can sink or source is 8mA per output pin.
