3-TO-8 LINE DECODERS /

DEMULTIPLEXERS



DESCRIPTION

The U74HC138 decodes a three-bit Address to 1-of-8 active-low

outputs.

This device features three Chip Select inputs, two active-low

and one active-high, to facilitate the demultiplexing, cascading,

and chip-selecting functions.

The demultiplexing function is accomplished by using the

address inputs to select the desired device output. One of the Chip

Selects is used as a data input while the other Chip Selects are

held in their active states.


