74LCX138

Low Voltage 1-of-8 Decoder/Demultiplexer

with 5V Tolerant Inputs

General Description

The LCX138 is a high-speed 1-of-8 decoder/demultiplexer.

This device is ideally suited for high-speed memory chip

select address decoding. The multiple input enables allow

parallel expansion to a 1-of-24 decoder using just three

LCX138 devices or a 1-of-32 decoder using four LCX138

devices and one inverter.

The 74LCX138 is fabricated with advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.
