Fault Protected, Extended CMR, RS-485/RS-422
Transceivers with Cable Invert and ±16.5kV ESD
ISL32483E, ISL32485E
The ISL3248xE 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 fault protected up to ±60V and
are protected against ±16.5kV ESD strikes without latch-up.
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 fault-protected RS-485 family one of the most robust on
the market.
Transmitters (Tx) deliver an exceptional 2.5V (typical)
differential output voltage into the RS-485 specified 54 load.
This yields better noise immunity than standard RS-485 ICs or
allows up to six 120 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.
The ISL32483E and ISL32485E include cable invert functions
that reverse the polarity of the Rx and/or Tx bus pins in case
the cable is misconnected. Unlike competing devices, Rx full
fail-safe operation is maintained even when the Rx input
polarity is switched.
For fault protected RS-485 transceivers without the cable
data sheets.
