Note 1:  The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The "Recommended Operating Conditions" table will define the conditions for actual device operation.

  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 DM74ALS137 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.
