ISL31470E, ISL31472E, ISL31475E, ISL31478E
Fault Protected, Extended Common Mode Range, RS-485/RS-422 Transceivers FN7639
Rev 1.00
September 3, 2015 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 В±60V.
Additionally, these transceivers operate in
environments with common mode voltages up to
В±15V (exceeds the RS-485 requirement), making
this RS-485 family one of the more robust on the
market. Features 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 topologies. Hot Plug Circuitry -Tx and Rx Outputs Remain
Three-State During Power-up/Power-down 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 …
