Theπ220N31/π221N31devices are low-power bidirectional isolators compatible with the I2C interface and are based on iDivider technology from 2PaiSemi.These devices have logic input andoutput buffers that are separated by using a silicon dioxide (SiO2) barrier.These devicesblock high voltages and prevent noise currents from entering the control side ground, avoiding circuit interference and damaging sensitive components.
The π220N31/π221N31devicesare based on iDividertechnologywith functional, performance, size, and power consumption advantages as compared to optocouplers.
The π220N31provides two bidirectional channels, supporting a complete isolated I2C interface. The π221N31provides one bidirectional channel and one unidirectional channel for applica-tions where a bidirectional clock is not required.Theπ221N31is usedin applicationsthat have a single master while the π220N31issuitable for multi-master applications.
