HD74LS156 Dual 2-line-to-4-line Decoders / Demultiplexers (with open collector outputs) REJ03D0441-0300 Rev.3.00 Jul.13.2005 This circuit features dual 1-line-to-4-line demultiprexer with individual strobes and common binary-address input. When both sections are enabled by the strobes, the common binary-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 1C is inverted through its outputs. The inverter following the 1C data input permits use as a 3-to-8-line decoder or 1-to-8-line demultiplexer without external gating.
