DATASHEET ISL32450E, ISL32452E, ISL32453E, ISL32455E, ISL32457E, ISL32458E, ISL32459E ±60V Fault Protected, 3.3V to 5V, ±20V Common-Mode Range, RS-485/RS-422 Transceivers with Cable Invert and ±15kV ESD FN7921 Rev.3.00 Feb 14, 2019 The ISL32450E, ISL32452E, ISL32453E, ISL32455E, ISL32457E, ISL32458E, and ISL32459E 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 common-mode voltages up to ±20V (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 log...
