XR5486E-5488E
ULTRA HIGH SPEED RS-485/RS-422 PROFIBUS TRANSCEIVERS WITH 1/8TH UNIT LOAD
AND +/-15KV ESD-PROTECTION
AUGUST 2011
REV. 1.0.2
GENERAL DESCRIPTION
The XR5486E-XR5488E family of RS-485 devices
are designed for reliable, bidirectional communication
on multipoint bus transmission lines. Each device
contains one differential driver and one differential
receiver. XR5488E is a half-duplex device while the
other part numbers are full-duplex. All devices comply
with TIA/EIA-485 and TIA/EIA-422 standards. Lead-
free and RoHS compliant packages are available for
all models.
These devices are ruggedized for use in harsh
operating conditions over the entire common mode
voltage range from -7V to +12V. Receivers are
specially designed to fail-safe to a logic high output
state if the inputs are left un-driven or shorted. All RS-
485 bus-pins are protected against severe ESD
events up to +/-15kV Air-Gap (IEC-61000-4-2), up to
+/-8kV Contact Discharge (IEC-61000-4-2) and up to
+/-15kV Human body Model. Drivers are protected
from excess current flow caused by bus contention or
output short-circuits by both an internal current limit
and a thermal-overload shutdown. Devices are rated
for
Industrial
(-40°C
to
+85°C)
operating
temperatures. Receivers have exceptionally high
input impedance, which places only 1/8th the
standard load on a bus. Up to 256 transceivers may
coexist while preserving full signal margin.
All devices operate from a single 5.0V power supply
and draw negligible quiescent power.
All versions
except the XR5487E may independently enable and
disable their driver and receiver and enter a low
power shutdown mode if both driver and receiver are
disabled. All outputs maintain high impedance in
shutdown or when powered-off.
