74LVC138A 3-to-8 line decoder/demultiplexer; inverting Rev.

The 74LVC138A features three enable inputs (E1, E2 and E3).
Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.
This multiple enable function allows easy parallel expansion of the 74LVC138A to a 1-of-32 (5 to 32 lines) decoder with just four 74LVC138A ICs and one inverter.
