The SNx4HC244 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 SNx4HC244 devices
are organized as two 4-bit buffers and drivers with separate output-enable
(OE) inputs. When OE is low, the device passes
noninverted data from the A inputs to the Y outputs. When OE is high,
the outputs are in the high-impedance state.
