description/ordering information  
GND 10  
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 ’HCT240 devices 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.
