    Per JESD 17
    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 ’AHC240 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.
