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 
(active-low output-enable) inputs, and complementary OE
and inputs.
The ´F240 is organized as two 4-bit buffers/line drivers with
separate output enable ()
inputs. When is low, the
device passes data from the A inputs to the Y outputs. When 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.
