Functional Description
The LVX138 high-speed 1-of-8 decoder/demultiplexer
accepts three binary weighted inputs (A
0
, A
1
, A
2
) and,
when enabled, provides eight mutually exclusive active-
LOW outputs (O
0
–
O
7
). The LVX138 features three Enable
inputs, two active-LOW (E
1
, E
2
) and one active-HIGH (E
3
).
All outputs will be HIGH unless E
1
and E
2
are LOW and E
3
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.
