These octal buffers and line drivers are designed  
specifically to improve both the performance and  
density of three-state memory address drivers,  
clock drivers, and bus-oriented receivers and  
transmitters. The designer has a choice of  
selected combinations of inverting and  
noninverting outputs, symmetrical, active-low  
output-control (G) inputs, and complementary  
output-control (G and G) inputs. These devices  
featurehighfan-out, improvedfan-in, and400-mV  
noise margin. The SN74LS’ and SN74S’ devices  
can be used to drive terminated lines down to  
133 .
