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 ’HC241 are organized as two
4-bit buffers/drivers with separate output-enable
(1OE and 2OE) inputs. When 1OE is low or 2OE
is high, the device passes noninverted data from
the A inputs to the Y outputs. When 1OE is high or
2OE is low, the outputs for the respective
buffers/drivers are in the high-impedance state.
