***as Instr.: The ISO1540-Q1 and ISO1541-Q1 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-Q1 and ISO1541-Q1 devices enable a complete isolated I2C interface to be implemented within a small form factor.

***AS INTRUMENTS: The ISO1540-Q1 has two isolated bidirectional channels for clock and data lines while the ISO1541-Q1 has a bidirectional data and a unidirectional clock channel. The ISO1541-Q1 is useful in applications that have a single controller while the ISO1540-Q1 is suitable for multi-controller applications. For applications where clock stretching by the target is possible, the ISO1540-Q1 device should be used.

***OMO Electronic: 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.

ISO1540QDRQ1 More Information

ISO154x/-Q1 Low-Power Bidirectional Isolators: OMO Electronic ISO154x/ISO154x-Q1 low-power, bidirectional isolators are compatible with I²C interfaces. These TI devices have their logic input and output buffers separated by TI's Capacitive Isolation technology using a silicon dioxide (SiO2) barrier. When used in conjunction with isolated power supplies, IS0154x/ISO154x-Q1 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 opto-couplers. The ISO154x/ISO154x-Q1 enable a complete isolated I²C interface to be implemented within a small form factor. ISO1540/-Q1 has two isolated bidirectional channels for clock and data lines while ISO1541/-Q1 has a bidirectional data and a unidirectional clock channel. ISO1541/-Q1 is useful in applications that have a single master while ISO1540/-Q1 is ideally fit for multi-master applications. The ISO154x-Q1 devices are AEC-Q100 qualified for automotive applications.Learn More
