Low Power, 3.0kV rms 2Pai Semi 2 Dual I C Isolators Data Sheet 220N31/221N31 The 220N31 provides two bidirectional channels, supporting a FEATURES 2 2 complete isolated I C interface. The 221N31 provides one Bidirectional I C communication bidirectional channel and one unidirectional channel for applica- Ultra-low power consumption tions where a bidirectional clock is not required. The 221N31 is Supports up to 2MHz operation used in applications that have a single master while the 220N31 Open-drain interfaces is suitable for multi-master applications. Side 1 outputs with 3.5 mA sink current These devices feature independent 3.0V to 5.5V supplies on each Side 2 outputs with 35 mA sink current side of the isolator. These devices operate from DC to 2MHz at 3.0V to 5.5V supply/logic levels ambient temperatures of -40C to +125C.
