Checking for live stock

The Texas Instruments ISO1541D is a high-performance I²C digital isolator, providing safe isolation of 2.5 kVrms across interface lines, ensuring galvanic separation for sensitive systems. This robust component delivers reliable, high-speed I²C isolation with safety ratings and immunity levels that exceed those of generic isolators. Its compact SMD footprint and robust electrical specs make it the go-to choice for engineers designing isolated communication links in industrial controls, smart metering, and embedded systems where safety and signal integrity are essential.

Product Core Features

Isolation Voltage: 2.5 kVrms (working), certified to 4242 VPK per DIN EN IEC 60747‑17.
Data Rate: Up to 1 Mbps, ideal for high‑speed I²C applications.
Transient Immunity (CMTI): ≥ 25 kV/µs, ensuring robustness against rapid noise transients.
ESD Protection: HBM ESD resistance of 4 kV (all pins) and 8 kV on bus pins.
Supply Voltage: Operates from 3 V to 5.5 V, suitable for both 3.3 V and 5 V systems.
Operating Temperature Range: −40°C to +125°C, robust across industrial environments.
Package / Material: Compact 8‑SOIC (surface mount), width approx. 3.9 mm.

Exceptional Advantages to Users
