description  
These octal buffers and line drivers are designed  
specifically to improve the performance and  
density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and  
transmitters by eliminating the need for 3-state  
overlap protection. The designer has a choice of  
selected combinations of inverting and  
noninverting outputs, symmetrical active-low  
output-enable (OE) inputs, and complementary  
OE and OE inputs. These devices feature high  
fan-out and improved fan-in.
