description
The SN54ALS137, SN74ALS137A, and
′AS137
are 3-line to 8-line decoders/demultiplexers with
latches on the three address inputs. When the
latch-enable (LE) input is low, the SN54ALS137,
SN74ALS137A,
and
′AS137
act
as
a
decoder/demultiplexer. When LE goes from low to
high, the address present at the select (A, B, and
C) inputs is stored in the latches. Further address
changes are ignored as long as LE remains high.
The output-enable (OE1 and OE2) inputs control
the outputs independently of the select or
latch-enable inputs. All of the outputs are forced
high if OE1 is low or OE2 is high. The
SN54ALS137, SN74ALS137A, and
′AS137 are
ideally
suited
for
implementing
glitch-free
decoders in strobed (stored-address) applications
in bus-oriented systems.
The
SN54ALS137
and
SN54AS137
are
characterized for operation over the full military
temperature range of – 55
°C to 125°C. The
SN74ALS137A
and
SN74AS137
are
characterized for operation from 0
°C to 70°C.
