Fault Protected, Extended Common Mode Range,
RS-485/RS-422 Transceivers
ISL31470E, ISL31472E, ISL31475E, ISL31478E
The ISL31470E, ISL31472E, ISL31475E, ISL31478E are
fault protected, extended common mode range
differential transceivers that exceed the RS-485 and
RS-422 standards for balanced communication. The
RS-485 bus pins (driver outputs and receiver inputs)
are protected against overvoltages up to ±60V.
Additionally, these transceivers operate in environments
with common mode voltages up to ±15V (exceeds the
RS-485 requirement), making this RS-485 family one
of the more 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
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 feature high drive levels - typically
15mA @ VOL = 1V (to ease the design of opto-coupled
isolated interfaces).
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.
