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
transmitters. The ’HCT244 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.
