Fault Protected, Extended Common Mode Range,
RS-485/RS-422 Transceivers with ±16.5kV ESD
ISL32470E, ISL32472E, ISL32475E, ISL32478E
The ISL32470E, ISL32472E, ISL32475E, ISL32478E 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 fault protected against overvoltages up to
±60V and are protected against ±16.5kV ESD strikes without
latch-up. Additionally, these transceivers operate in environments
with common mode voltages up to ±15V (exceeds the RS-485
requirement), making this fault-protected RS-485 family one of
the more 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 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
features and configurations by device number.
For a fault-protected RS-485 transceiver with a ±25V extended
common mode range, please see the
data sheets.
