Dual 2-Line to 4-Line Decoders/Demultiplexers  
Features  
General Description  
Y
Applications:  
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.
