The 'LS137 is a three-line to eight-line decoder/demultiplexer with latches
on the three address inputs. When the latch-enable input (GL\) is
low, the 'LS137 acts as a decoder/demultiplexer. When GL\ goes from
low to high, the address present at the select inputs (A, B, and C) is stored
in the latches. Further address changes are ignored as long as GL\
remains high. The output enable controls, G1 and G\2, control the
state of the outputs independently of the select or latch-enable inputs. All
of the outputs are high unless G1 is high and G\2 is low. The 'LS137
is ideally suited for implementing glitch-free decoders in strobed (stored-address)
applications in bus-oriented systems.
