Introduction

The CEU8722N1/CEU8722N0 series are high-speed, high-reliability dual-channel magnetic isolation universal digital isolators, meeting 3.0kVRMS isolation withstand voltage capability per UL-1577 standard. Signal transmission is achieved using chip-scale micro-transformers with proprietary AdaptivePulse modulation/demodulation technology, combining the timing accuracy of edge modulation with the robustness of on-off keying (OOK) modulation. The device includes 1 forward signal channel and 1 reverse signal channel, with a typical signal propagation delay of less than 9 ns. A power-loss protection function is provided: when the input is powered off or floating, CEU8722N1 defaults to a high output level, while CEU8722N0 defaults to a low output level.
