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.
