description/ordering information
These octal bus transceivers are designed
specifically for low-voltage (3.3-V) VCC operation,
but with the capability to provide a TTL interface
to a 5-V system environment.

These devices are designed for asynchronous
communication between data buses. They
transmit 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 devices so the buses are effectively isolated.
