3 Description
These octal bus transceivers are designed for
asynchronous two-way communication between data
buses. The control-function implementation minimizes
external timing requirements.
The 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 are
effectively isolated.
