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
direction-control (DIR) input. The output-enable
(OE) input can disable the device so that the
buses are effectively isolated.
