Interface & Connectivity

Overview

Description

The ISL32745E is a galvanically isolated, high-speed differential bus transceiver, designed for full-duplex 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 ISL32745E delivers a minimum differential output voltage of 2. 1V across a 54Ω differential load for high noise immunity and excellent data integrity. 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 a simple interface to local controllers. 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 open (floating) or shorted.
