These octal buffers and line drivers are designed  
specifically to improve both the performance and  
density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and  
transmitters. The ’HC240 are organized as two  
4-bit buffers/drivers with separate output-enable  
(OE) inputs. When OE is low, the device passes  
inverted data from the A inputs to the Y outputs.  
When OE is high, the outputs are in the  
high-impedance state.
