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 ’HC241 are organized as two  
4-bit buffers/drivers with separate output-enable  
(1OE and 2OE) inputs. When 1OE is low or 2OE  
is high, the device passes noninverted data from  
the A inputs to the Y outputs. When 1OE is high or  
2OE is low, the outputs for the respective  
buffers/drivers are in the high-impedance state.
