MIKROE I2C Isolator Click

MIKROE I2C Isolator Click carries ISO1540 a low-power bidirectional isolator compatible with I2C interfaces. On the board the Texas Instruments chip is connected to two sets of I2C pins one on the mikroBUS™ connector (SDA SCL) the other on the upper edge of the board (SCL2 SDL2). ISO1540 uses a silicon dioxide barrier that separates the logic input and output buffers. Bidirectional isolators based on TI’s Capacitive Isolation technology have many advantages over opto-couplers (performance size power consumption etc.). When used together with isolated power supplies they block high voltages isolate grounds and prevent interference from from noise currents.
