±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
@ V
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.
