When both sections are Dual 1-to-4-line demultiplexer enabled by the strobes, the common address inputs 3-to-8-line decoder sequentially select and route associated input data to the appropriate output of each section. The individual strobes 1-to-8-line demultiplexer permit activating or inhibiting each of the 4-bit sections as � Individual strobes simplify cascading for decoding or desired. Data applied to input C1 is inverted at its outputs demultiplexing larger words and data applied at C2 is true through its outputs. The � Input clamping diodes simplify system design inverter following the C1 data input permits use as a 3-to-8- � Choice of outputs: line decoder, or 1-to-8-line demultiplexer, without external Totem-pole (DM74LS155) gating. Input clamping diodes are provided on these cir- cuits to minimize transmission-line effects and simplify sys- Open-collector (DM74LS156) tem design.
