Introduction

High-speed, high-reliability dual-channel magnetic isolation universal digital isolator with 3.0 kVrms isolation withstand voltage per UL-1577. Utilizes chip-scale micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, combining the timing accuracy of edge modulation with the robustness of on-off keying (OOK) modulation. Features 2 forward signal channels and 0 reverse signal channels, with typical signal propagation delay under 9 ns. Provides power-loss protection: when the input is unpowered or floating, CEU8420N1 defaults to a high output level and CEU8420N0 defaults to a low output level.
