description/ordering information
These
octal
buffers/drivers
are
designed
specifically to improve the performance and
density of 3-state memory-address drivers, clock
drivers,
and
bus-oriented
receivers
and
transmitters.
The ’AHCT240 devices are organized as two 4-bit
buffers/line drivers with separate output-enable
(OE) inputs. When OE is low, the device passes
data from the A inputs to the Y outputs. When OE
is high, the outputs are in the high-impedance
state.
To ensure the high-impedance state during power
up or power down, OE should be tied to VCC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
