Bus I/O Protection
–
–
> ±15kV HBM protection
DESCRIPTION
These devices have robust 3.3V drivers and receivers
> ±12kV IEC61000-4-2 Contact Discharge
•
•
•
•
Extended Industrial Temperature Range
–40°C to 125°C
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.
Large Receiver Hysteresis (80 mV) for Noise
Rejection
Low Unit-loading allows over 200 connected
nodes
These devices each combine 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 all
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.
Low Power Consumption
