Dual 2-Line to 4-Line Decoders/Demultiplexers
General Description
These TTL circuits feature dual 1-line-to-4-line demultiplex-
ers 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 cir-
cuits to minimize transmission-line effects and simplify sys-
tem design.
