DESCRIPTION
These bus transceivers are designed for a synchronous three-way communication between four-line data buses. They give the designer a choice of selecting inverting, noninverting or a combination of inverting and noninverting data paths with 3-state outputs. The port for any bus selected for input and any other bus not enabled for output will be at high impedance.FEATURES
