74LCX138 Datasheet Low Voltage 1-of-8 Decoder/demultiplexer

Manufacturer: Fairchild (now onsemi)

Overview: 74LCX138 Low Voltage 1-of-8 Decoder/Demultiplexer with 5V Tolerant Inputs March 1995 Revised December 2013 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.
