FEATURES
APPLICATIONS
• Small-size MSOP Packages Save Board Space, • Factory Automation
or SOIC for Drop-in Compatibility
• Telecomm Infrastructure
• Bus I/O Protection
• Motion Control
– > ±15kV HBM protection
DESCRIPTION
– > ±12kV IEC61000-4-2 Contact Discharge
These devices have robust 3.3V drivers and receivers
• Extended Industrial Temperature Range
in a small package for demanding industrial
–40°C to 125°C
applications. The bus pins are robust to ESD events,
• Large Receiver Hysteresis (80 mV) for Noise
with high levels of protection to Human-Body Model
Rejection
and IEC Contact Discharge specifications.
• Low Unit-loading allows over 200 connected
These devices each combine a differential driver and
nodes
a differential receiver, which operate from a single
3.3-V power supply. The driver differential outputs
• Low Power Consumption
and the receiver differential inputs are connected
– Low Standby Supply Current: < 2 µA
internally to form a bus port suitable for half-duplex
– I

<1 mA Quiescent During Operation
(two-wire bus) communication. These devices all
• 5V-Tolerant Logic Inputs Compatible With feature a wide common-mode voltage range making
the devices suitable for multi-point applications over
3.3 V or 5 V Controllers
long cable runs. These devices are characterized
• Signaling Rate Options Optimized for:
from -40°C to 125°C.
