High speed universal digital isolators coileasy CEU8730U0W with adaptive pulse modulation and wide body SOW 16 packaging
Product Overview
The CEU8730U1W/CEU8730U0W are high-speed, high-reliability, three-channel, magnetically isolated universal digital isolators. They meet the 5.7 kVrms isolation withstand voltage standard (UL-1577) and are housed in a wide-body SOW-16 package. Utilizing chip-level microtransformers and proprietary AdaptivePulse modulation/demodulation technology, these isolators offer excellent timing accuracy for edge modulation and robustness for On-Off Keying (OOK) modulation. They feature a typical signal transmission delay of less than 10 ns and common-mode transient immunity of 200 kV/s. The devices include 3 forward signal channels and 0 reverse signal channels. Both models offer power-down protection, with CEU8730U1W defaulting to a high output level and CEU8730U0W defaulting to a low output level when the input is powered down or floating.
