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 in-
puts in a single 16-pin package When both sections are
enabled by the strobes the common address inputs se-
quentially select and route associated input data to the ap-
propriate output of each section The individual strobes per-
mit activating or inhibiting each of the 4-bit sections as de-
sired 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 de-
coder or 1-to-8-line demultiplexer without external gating
Input clamping diodes are provided on these circuits to mini-
mize transmission-line effects and simplify system design
