DM74LS155 • DM74LS156 Dual 2-Line to 4-Line Decoders/Demultiplexers August 1986 Revised April 2000 DM74LS155 • DM74LS156 Dual 2-Line to 4-Line Decoders/Demultiplexers General Description These TTL circuits feature dual 1-line-to-4-line demultiplexers with individual strobes and common binary-address inputs in a single 16-pin package. When both sections are enabled by the strobes, the common address inputs sequentially select and route associated input data to the appropriate output of each section. The individual strobes permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input C1 is inverted at its outputs and data applied at C2 is true through its outputs.
