description  
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. Taken together with the ′F241 and  
′F244, these devices provide the choice of  
selected combinations of inverting and  
noninverting outputs, symmetrical OE (active-low  
output-enable) inputs, and complementary OE  
and OE inputs.

The ′F240 is organized as two 4-bit buffers/line  
drivers with separate output enable (OE) inputs.  
When OE is low, the device passes data from the  
A inputs to the Y outputs. When OE is high, the  
outputs are in the high-impedance state.

The SN74F240 is available in TI’s shrink  
small-outline package (DB), which provides the  
same I/O pin count and functionality of standard  
small-outline packages in less than half the  
printed-circuit-board area.  
The SN54F240 is characterized for operation over  
the full military temperature range of –55°C to  
125°C. The SN74F240 is characterized for  
operation from 0°C to 70°C.
