description/ordering information
These octal buffers/drivers are designed for 2-V to
5.5-V V
CC
operation.
The ’LV240A devices are designed specifically to
improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters.
These devices are 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.
