ISO1540 Datasheet (Texas Instruments) - Low-Power Bidirectional I2C Isolators

ISO1540, Low-Power Bidirectional I2C Isolators

The ISO1540 and ISO1541 devices are low-power, 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.
