HD74HC444 (HD74HC442 - HD74HC444) Quad. Tridirectional Bus Transceiver(with noninverted/inverted 3-state outputs)

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 S 0 and S1 inputs select the bus from w.
