DM74ALS137
3 to 8 Line Decoder/Demultiplexer with Address Latches
General Description
The ALS137 is a three line to eight line decoder/demulti-
plexer with latches on the three address inputs. When the
latch-enable input (GL) is LOW, the ALS137 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 G2, 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 G2 is LOW. The ALS137 is
ideally suited for implementing glitch-free decoders in
strobed (stored-address) applications in bus-oriented sys-
tems.
