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 at 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 3 for
key features and configurations by device number.
For fault protected or wide common mode range devices with
cable invert (polarity reversal) please see the ISL32485E
datasheet.
