HD74LS155
Dual 2-line-to-4-line Decoders / Demultiplexers
REJ03D0440–0200
Rev.2.00
Feb.18.2005
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.
