HD74HC442 Datasheet Quad. Tridirectional Bus Transceiver

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC442/HD74HC443/HC74HC444 Quad. Tridirectional Bus Transceiver (with noninverted 3-state outputs) Quad.

General Description

These bus transceivers are designed for a synchronous three-way munication between four-line data buses.

They give the designer a choice of selecting inverting, noninverting or a bination of inverting and noninverting data paths with 3-state outputs.

The S 0 and S1 inputs select the bus from which data are to be transferred.
