ISO1541-Q1 - Low-Power Bidirectional I2C Isolators

Download the ISO1541-Q1 datasheet PDF. This datasheet also covers the ISO1540-Q1 variant, as both devices belong to the same low-power bidirectional i2c isolators family and are provided as variant models within a single manufacturer datasheet.

General Description

The ISO1540-Q1 and ISO1541-Q1 devices are lowpower, bidirectional isolators that are compatible with I2C interfaces.

These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2) barrier.

Key Features

  • Qualified for automotive.
