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.
