Description

The ISL32705E is a galvanically isolated, full-duplex differential bus transceiver, designed for bidirectional data transmission meeting the RS-485 and RS-422 standards for balanced communication. All bus terminals are protected against ±7kV ESD strikes without latch-up. The device uses Giant Magnetoresistance (GMR) as isolation technology. A unique ceramic/polymer composite barrier provides excellent isolation and nearly unlimited barrier life. The part is available in a 16 Ld wide-body SOIC package providing true 8mm creepage distance. The ISL32705E delivers a minimum of 1. 5V into a 54Ω differential load for excellent data integrity over long cable lengths. The device is compatible with 3V and 5V input supplies, allowing an interface to standard microcontrollers without additional level shifting. Current limiting and thermal shutdown features protect against output short-circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a “fail-safe if open” design, ensuring a logic high R-output if A/B are floating.
