  • Overview
    ISO1540D Product overview

    The ISO1540D is a Bidirectional Isolator compatible with I²C interface. It has their logic input and output buffers separated by TI"s Capacitive Isolation technology using a silicon dioxide (SiO2) barrier. When used with isolated power supplies, it blocks high voltages, isolate grounds and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry. This isolation technology provides for function, performance, size and power consumption advantages when compared to optocouplers. This device enables a complete isolated I²C interface to be implemented within a small form factor. Isolated bidirectional communications is accomplished within these devices by offsetting the side 1 low-level output voltage to a value greater than the side 1 high-level input voltage, thus preventing an internal logic latch that otherwise would occur with standard digital isolators.

    ISO1540DR Product overview

    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. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry. This isolation technology provides for function, performance, size, and power consumption advantages when compared to optocouplers. The ISO1540 and ISO1541 devices enable a complete isolated I2C interface to be implemented within a small form factor. The ISO1540 has two isolated bidirectional channels for clock and data lines while the ISO1541 has a bidirectional data and a unidirectional clock channel. The ISO1541 is useful in applications that have a single master while the ISO1540 is suitable for multi-master applications. For applications where clock stretching by the slave is possible, the ISO1540 device should be used. Isolated bidirectional communication is accomplished within these devices by offsetting the low-level output voltage on side 1 to a value greater than the high-level input voltage on side 1, thus preventing an internal logic latch that otherwise would occur with standard digital isolators.
