DEMULTIPLEXERS

DESCRIPTION

The U74HCT138 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.

FEATURES

* Operate from 4.5V to 5.5V

* Low Input Current:1.0uA Max

* Low Power Consumption: 8μA Max

* Inputs are TTL voltage compatible
