High speed digital isolator coileasy CEU8722U1W with adaptive pulse modulation and default high output level
CEU8722U1W/CEU8722U0W Digital Isolator
The CEU8722U1W/CEU8722U0W series are high-speed, high-reliability, dual-channel, wide-body digital isolators with 5.7 kVRMS isolation withstand voltage capability according to UL-1577. They utilize chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, balancing the timing accuracy of edge modulation with the robustness of On-Off Keying (OOK) modulation. These isolators offer a default power-down protection function, with CEU8722U1W defaulting to a high output level and CEU8722U0W to a low output level when the input is powered down or floating. Applications include smart meters, industrial automation, home appliances, and isolated data buses.
