DM54155/DM74155 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. The inverter following the C1 data input permits use as a 3-to-8-line decoder, or 1-to-8-line
demultiplexer, without external gating. Input clamping diodes are provided on these circuits to
minimize transmission-line effects and simplify system design.
