General Description

Both circuits have three binary select inputs (A0, A1 and A2) that can be latched by an active High Latch Enable (LE) signal to isolate the outputs from select-input changes.

A “Low” LE makes the output transparent to the input and the circuit functions as a one-of-eight decoder.

Two Output Enable inputs (OE1 and OE0) are provided to simplify cascading and to facilitate demultiplexing.
