Mar 1, 2012 В±40V Fault Protected, 3.3V to 5V, В±15V Common Mode Range, RS-485/RS-422
Transceivers With Cable Invert and В±15kV ESD
The ISL32430E through ISL32437E are 3.3V to 5V powered,
fault protected, extended common mode range differential
transceivers for balanced communication. The RS-485 bus pins
(driver outputs and receiver inputs) are protected against
overvoltages up to В±40V, and against В±15kV ESD strikes.
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.
Transmitters are RS-485 compliant with VCC ≥ 4.5V and
deliver a 1.1V differential output voltage into the RS-485
specified 54О© load even with VCC = 3V.
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 full fail-safe
operation is maintained even when the Rx input polarity is
switched (cable invert function on ISL32437E).
The ISL32437E includes a cable invert function that reverses …
