Description

The ISL32430E, ISL32432E, ISL32433E, ISL32435E, and 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 ±40V and against ±15kV ESD strikes. 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 most robust on the market. The transmitters are RS-485 compliant with VCC ≥ 4. 5V and deliver a 1. 1V differential output voltage into the RS-485 specified 54Ω load even with VCC = 3V. The receiver (Rx) inputs feature a full fail-safe design that ensures a logic high Rx output if the Rx inputs are floating, shorted, or on a terminated but undriven (idle) bus. The 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 the polarity of the Rx and Tx bus pins if the cable is misconnected during installation.
