DESCRIPTION  
The ISO1540 and ISO1541 are low-power, bidirectional isolators that are compatible with I2C interfaces. These  
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, 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 opto-couplers. The ISO1540 and ISO1541 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 ideally fit for multi-master applications.  
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.
