description/ordering information
These octal bus transceivers are designed for asynchronous two-way communication between data buses. The
control-function implementation minimizes external timing requirements.
The ’AHCT245 devices allow data transmission 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. The output-enable (OE) input can be used to
disable the device so that the buses effectively are 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.
