description/ordering information

These octal bus transceivers are designed

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.
