The maximum frequency of operation for the 74LVC138APW,118 is 100 MHz.
To ensure proper power supply, connect VCC to a 1.65 V to 5.5 V power source, and GND to a reliable ground connection. Also, decouple the power supply with a 0.1 μF capacitor.
The 74LVC138APW,118 can sink or source up to 24 mA of current per output pin.
The enable inputs (E1, E2, E3) are active-low, meaning that the decoder is enabled when the input is LOW. Connect unused enable inputs to VCC or GND as required.
The propagation delay of the 74LVC138APW,118 is typically 3.5 ns at 25°C and 3.3 V supply voltage.
