3 Description

These devices have robust 3.3-V drivers and

receivers in a small package for demanding industrial

applications. The bus pins are robust to ESD events

with high levels of protection to Human-Body Model

and IEC Contact Discharge specifications.

Each of these devices combines a differential driver

and a differential receiver which operate from a single

3.3-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. These devices feature

a wide common-mode voltage range making the

devices suitable for multi-point applications over long

cable runs. These devices are characterized from

–40°C to 125°C.
