Description
These bus transceivers are designed for a synchronous three-way communicatieen four-line data buses. They
give the designer a choice of selecting inverting, noninverting or a combinag and noninverting data paths
with 3-state outputs.
The S0 and S1 inputs select the bus from which data are to be transthe bus or buses to which
data are to be transferred. The port for any bus selected for inpbled for output will be at
high impedance.
