High reliability dual channel digital isolator coileasy CEU8722N1 with UL 1577 and CQC certifications
Product Overview
The CEU8722N1/CEU8722N0 series are high-speed, high-reliability dual-channel magnetically isolated universal digital isolators, meeting UL-1577 standard with 3.0 kVRMS isolation withstand voltage. Utilizing chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology, they offer a balance of edge modulation timing precision and On-Off Keying (OOK) modulation robustness. Each device features one forward and one reverse signal channel with a typical signal transmission delay of less than 9 ns. The series provides power-down protection, with CEU8722N1 defaulting to a high output level and CEU8722N0 to a low output level when input power is lost or floating.
