description

These octal bus transceivers are designed for

asynchronous two-way communication between

data buses. The control-function implementation

minimizes external timing requirements.

20 19

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 disable the device so that the

buses are effectively isolated.
