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.
Features
s Input voltage level translation from 5V to 3V
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance

Functional Description
The LVX138 high-speed 1-of-8 decoder/demultiplexer
accepts three binary weighted inputs (A0, A1, A2) and,
when enabled, provides eight mutually exclusive active-
LOW outputs (O0–O7). The LVX138 features three Enable
inputs, two active-LOW (E1, E2) and one active-HIGH (E3).
All outputs will be HIGH unless E1 and E2 are LOW and E3
is HIGH.
The LVX138 can be used as an 8-output demultiplexer by
using one of the active LOW Enable inputs as the data
input and the other Enable inputs as strobes. The Enable
inputs which are not used must be permanently tied to their
appropriate active-HIGH or active-LOW state.
