The XR33052, XR33053, XR33055, XR33058, XR33152, XR33155,
XR33156 and XR33158 are a family of high performance RS-485/
RS-422 transceivers designed for improved performance in noisy
industrial environments and increased tolerance to system faults.
The analog bus pins can withstand direct shorts up to ±60V and are
protected against ESD events up to ±15kV HBM. An extended ±25V
common mode operating range allows for more reliable operation in
noisy environments. These transceivers feature a wide supply voltage
range (3.0V to 5.5V) and operate at maximum data rates of 250kbps
(XR33152, XR33052), 1Mbps (XR33053, XR33055, XR33155) and
20Mbps (XR33058, XR33156, XR33158). The XR33156 features
a 1.65V to 5.5V I/O logic supply, simplifying multi-voltage system
interfacing requirements and an invert pin to compensate for reversed
polarity on bus pins.
The family includes several inherent protection features including
overload protection and enhanced receiver fail-safe protection for open,
shorted, or terminated-but-idle data lines. The XR33156 and XR3305x
include hot swap glitch protection to prevent false transitions on the
bus during power up or live insertion and can enter a 1nA low current
shutdown mode for extreme power savings.
The transceivers feature the industry’s lowest standby current of 1nA
(typ), 1µA (max). The ±60V fault tolerance, wide operating voltage
range, flexible logic interface and low standby current make these
transceivers well suited for industrial control networks, HVAC networks,
building and process automation, energy metering and other industrial
applications. Multipoint applications over long cable runs will benefit
from the wide common mode voltage range of these transceivers.
