±60V Fault Protected, 5V, RS-485/RS-422
Transceivers with ±25V Common Mode Range
ISL31490E, ISL31491E, ISL31492E, ISL31493E, ISL31495E,
ISL31496E, ISL31498E
The ISL31490E, ISL31491E, ISL31492E, ISL31493E,
ISL31495E, ISL31496E, ISL31498E are fault protected,
5V powered, differential transceivers that exceed the
RS-485 and RS-422 standards for balanced
communication. The RS-485 transceiver pins (driver
outputs and receiver inputs) are protected against faults
up to ±60V. Additionally, the extended common mode
range allows these transceivers to operate in
environments with common mode voltages up to ±25V
(>2x the RS-485 requirement), making this RS-485
family one of the most robust on the market.
Transmitters deliver an exceptional 2.5V (typical)
differential output voltage into the RS-485 specified 54Ω
load. This yields better noise immunity than standard
RS-485 ICs, or allows up to six 120Ω terminations in star
network topologies.
Receiver (Rx) inputs feature a “Full Fail-Safe” design
which ensures a logic high Rx output if Rx inputs are
floating, shorted, or on a terminated but undriven (idle)
bus. Rx outputs have high drive levels - typically 15mA
@ VOL = 1V (for opto-coupled, isolated applications).
Half duplex (Rx inputs and Tx outputs multiplexed
together) and full duplex pinouts are available. See
Table 1 on page 2 for key features and configurations by
device number.
For fault protected or wide common mode range devices
with cable invert (polarity reversal) or logic supply (VL)
pins, please see the ISL31480E data sheet.

product reliability and result in failures not covered by warranty.
NOTES:
5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
6. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air.
7. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach”
features. See Tech Brief TB379 for details.
8. For θJC, the “case temp” location is taken at the package top center.
9. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Test Conditions: VCC = 4.5V to 5.5V; Unless Otherwise Specified. Typicals are at VCC = 5V,
