description/ordering information
The ’AC245 octal bus transceivers are designed
for
asynchronous
two-way
communication
between
data
buses.
The
control-function
implementation
minimizes
external
timing
requirements.
When the output-enable (OE) is low, the device
passes noninverted data from the A bus to the B
bus or from the B bus to the A bus, depending on
the logic level at the direction control (DIR) input.
A high on OE disables the device so that the buses
are effectively isolated.
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.
