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. With the ALS240A, ALS241C,  
AS240A,andAS241A, thesedevicesprovidethe  
choice of selected combinations of inverting  
outputs, symmetrical active-low output-enable  
(OE) inputs, and complementary OE and OE  
inputs.
