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.
