description

These octal bus transceivers are designed for

asynchronous two-way communication between

data buses. These devices transmit data from the

A bus to the B bus or from the B bus to the A bus,

depending upon the 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.
