description/ordering information (continued)

The ’LV245A devices are designed for asynchronous communication between data buses. The device

transmits 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. The output-enable (OE) input can be used to disable the device so the buses are

effectively isolated.

To ensure the high-impedance state during power up or power down, OE should be tied to V

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

through a pullup

These devices are fully specified for partial-power-down applications using I . The I circuitry disables the

off

outputs, preventing damaging current backflow through the devices when they are powered down.
