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 В±60V. Additionally, the extended
common mode range allows these transceivers to operate in
environments with common mode voltages up to В±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 54О© load. This yields
better noise immunity than standard RS-485 ICs, or allows up
to six 120О© terminations in star network topologies. FN7637
Rev 3.00
May 13, 2015 Features Fault protected RS-485 bus pins up to В±60V Extended common mode range В±25V
More than twice the range required for RS-485 1/4 unit load for up to 128 devices on the bus High transient overvoltage tolerance В±80V Full fail-safe (open, short, terminated) RS-485 receivers High Rx IOL for opto-couplers in isolated designs Hot plug circuitry -Tx and Rx outputs remain three-state
during power-up/power-down Choice of RS-485 data rates 250kbps to 15Mbps Receiver (Rx) inputs feature a “Full Fail-safe” design, which
ensures a logic high Rx output if Rx inputs are floating, shorted, …
