        DUAL 1-OF-4 DECODER/
        DEMULTIPLEXER
        The SN54/74LS155 and SN54/74LS156 are high speed Dual 1-of-4
        Decoder/Demultiplexers. These devices have two decoders with common
        2-bit Address inputs and separate gated Enable inputs. Decoder “a” has an
        Enable gate with one active HIGH and one active LOW input. Decoder “b” has
        two active LOW Enable inputs. If the Enable functions are satisfied, one
        output of each decoder will be LOW as selected by the address inputs. The
        LS156 has open collector outputs for wired-OR (DOT-AND) decoding and
        function generator applications.
        The LS155 and LS156 are fabricated with the Schottky barrier diode
        process for high speed and are completely compatible with all Motorola TTL
        families.
