ISO1541DR Description

Short technical summary and product information.

The ISO1541DR from Texas Instruments is a low-power, bidirectional digital isolator designed for I2C interfaces. It provides 2500Vrms of isolation, safeguarding systems from high voltages and noise. This device supports bidirectional data communication on one channel and unidirectional clock on another, with a maximum data rate of 1Mbps.

 

Key electrical characteristics include a working isolation voltage of 400Vrms and a surge isolation voltage of 4000Vpk. The ISO1541DR operates over a wide temperature range of -40°C to 125°C and features a supply voltage range of 3V to 5.5V. It is housed in a standard 8-SOIC package and is designed for surface mount applications.

 

Utilizing Texas Instruments' Capacitive Isolation technology with a silicon dioxide barrier, the ISO1541DR effectively blocks high voltages, isolates grounds, and prevents noise currents from entering local grounds. It offers ±50kV/µs transient immunity and HBM ESD protection of 4kV on all pins, with 8kV on bus pins.
