3 Description

This device has robust drivers and receivers for

demanding industrial applications. The bus pins are

robust to ESD events, with high levels of protection to

Human-Body Model, Air-Gap Discharge, and Contact

Discharge specifications.

The device combines a differential driver and a

differential receiver, which operate from a single 5-V

power supply. The driver differential outputs and the

receiver differential inputs are connected internally to

form a bus port suitable for half-duplex (two-wire bus)

communication. The device features a wide commonmode

voltage range making the device suitable for

multi-point applications over long cable runs. The

device is characterized from –40°C to 85°C.
