ISO1540 Overview
The ISO1540 and ISO1541 devices are low-power, bidirectional isolators that are patible 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...
