Quad Tridirectional Bus Transceiver

(with noninverted/inverted 3-state outputs)

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 S₀and S₁inputs select the bus from which data are to be transferred. The G inputs enable the bus or

buses to which data are to be transferred. The port for any bus selected for input and any other bus not

enabled for output will be at high impedance.
