description/ordering information
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 ’HC244
devices are organized as two 4-bit buffers/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.
