概要

The ISL32741E is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. The device uses giant magnetoresistance (GMR) as its isolation technology. The part is available in a 16 Ld SOICW package with true 8mm creepage distance. The ISL32741E is PROFIBUS compliant, including the rigorous PROFIBUS differential output voltage specifications. A unique ceramic/polymer composite barrier provides 6kV reinforced isolation and 44,000 years of barrier life. 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 are a full fail-safe design, ensuring a logic high R-output if A/B are floating or shorted.
