General Description
The MM74HCT138 decoder utilizes advanced silicon-gate CMOS technology, and are well suited to memory address decoding or data routing applications.

Both circuits feature high noise immunity and low power consumption usually associated with CMOS circuitry, yet have speeds comparable to low power Schottky TTL logic.
The MM74HCT138 have 3 binary select inputs (A, B, and C). If the device is enabled these inputs determine whichone of the eight normally HIGH outputs will go LOW.

Two active LOW and one active HIGH enables (G1, G2A and G2B) are provided to ease the cascading decoders.
