Introduction

CEU8742U1W/CEU8742U0W is a high-speed, high-reliability quad-channel magnetic isolation general-purpose digital isolator, meeting the 5.7kVrms isolation voltage rating per UL-1577 standard, housed in a wide-body SOW-16 package. It employs 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. Typical signal propagation delay is less than 10 ns, with a common-mode transient immunity of ±200 kV/μs. It integrates 2 forward signal channels and 2 reverse signal channels. A power-loss protection function is provided: when the input power is lost or floating, CEU8742U1W defaults to a high output level, while CEU8742U0W defaults to a low output level.
