Renesas Electronics Corporation ±60V Fault Protected, 3.3V to 5V, ±20V CMR, 1Mbps Half-Duplex RS-485/RS-422, ±15kV ESD ISL32455EIBZ

Description
The ISL3245xE are 3.3V to 5V powered, fault protected, extended Common-Mode Range (CMR) differential transceivers for balanced communication. The RS-485 bus pins (driver outputs and receiver inputs) are protected against overvoltages up to ±60V, and against ±15kV ESD strikes. These transceivers operate in environments with commonmode voltages up to ±20V (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 54O 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 ISL32457E and ISL32459E). The ISL32457E and ISL32459E include a cable invert function that reverses the polarity of the Rx and Tx bus pins in case the cable is misconnected during installation.
