FEATURES  
APPLICATIONS  
•
Small-size MSOP Packages Save Board Space,  
or SOIC for Drop-in Compatibility  
•
•
•
Factory Automation  
Telecomm Infrastructure  
Motion Control  
•
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  
–
–
Low Standby Supply Current: < 2 µA  
ICC <1 mA Quiescent During Operation  
•
•
5V-Tolerant Logic Inputs Compatible With  
3.3 V or 5 V Controllers  
Signaling Rate Options Optimized for:  
250 kbps, 20 Mbps, 50 Mbps
