74LVX138
Low Voltage 1-of-8 Decoder/Demultiplexer
General Description
The LVX138 is a high-speed 1-of-8 decoder/demultiplexer.
This device is ideally suited for high-speed bipolar memory
chip select address decoding. The multiple input enables
allow parallel expansion to a 1-of-24 decoder using just
three LVX138 devices or a 1-of-32 decoder using four
LVX138 devices and one inverter.
