Product Description

The Texas Instruments ISO1541DR digital isolator is a bidirectional I2C-compatible isolation device designed to provide robust galvanic isolation for communication interfaces. It features two independent isolation channels supporting bidirectional data transfer up to 1 MHz, operating within a wide voltage range of 1.71 V to 5.5 V on both input and output sides. The ISO1541DR integrates an internal oscillator and requires no external components, enabling direct interfacing with I2C modules. It operates reliably across an industrial temperature range of -40°C to +125°C, making it ideal for harsh environments in industries such as factory automation, medical systems, and power management. Key advantages include low propagation delay, high electromagnetic immunity, and compliance with safety standards. However, its data rate may limit high-speed applications. The device ensures signal integrity and protection against voltage surges, enhancing system reliability.
