Introduction

The CEU8722U1W/CEU8722U0W series are high-speed, high-reliability dual-channel magnetic isolation wide-body general-purpose digital isolators, meeting 5.7 kVRMS isolation voltage withstand capability per UL-1577 standard. Signal transmission employs chip-scale micro-transformers with proprietary AdaptivePulse modulation/demodulation technology, combining the timing precision of edge modulation with the robustness of on-off keying (OOK) modulation. Each 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 feature is provided: when the input power is lost or floating, CEU8722U1W defaults to a high output level, while CEU8722U0W defaults to a low output level.
