4-Line to 16-Line Decoder/Demultiplexer  
General Description  
Features  
Each of these 4-line-to-16-line decoders utilizes TTL cir-  
cuitry to decode four binary-coded inputs into one of six-  
teen mutually exclusive outputs when both the strobe  
inputs, G1 and G2, are LOW. The demultiplexing function  
is performed by using the 4 input lines to address the out-  
put line, passing data from one of the strobe inputs with the  
other strobe input LOW. When either strobe input is HIGH,  
all outputs are HIGH. These demultiplexers are ideally  
suited for implementing high-performance memory decod-  
ers. All inputs are buffered and input clamping diodes are  
provided to minimize transmission-line effects and thereby  
simplify system design.  
Decodes 4 binary-coded inputs into one of 16 mutually  
exclusive outputs  
Performs the demultiplexing function by distributing data  
from one input line to any one of 16 outputs  
Input clamping diodes simplify system design  
High fan-out, low-impedance, totem-pole outputs  
Typical propagation delay  
3 levels of logic 23 ns  
Strobe
