description
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 ’HC240 are organized as two
4-bit buffers/drivers with separate output-enable
(OE) inputs. When OE is low, the device passes
inverted data from the A inputs to the Y outputs.
When OE is high, the outputs are in the
high-impedance state.
