Product Overview

The CEU8720N1/CEU8720N0 series are high-speed, high-reliability dual-channel magnetically isolated universal digital isolators, meeting a 3.0 kVRMS isolation withstand voltage under UL-1577 standard. Utilizing chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, they balance the timing precision of edge modulation with the robustness of On-Off Keying (OOK) modulation. These devices feature 2 forward signal channels and 0 reverse signal channels, with a typical signal transmission delay of less than 9 ns. The CEU8720N1/CEU8720N0 series offers power-down protection, with CEU8720N1 defaulting to a high output level and CEU8720N0 defaulting to a low output level when input power is lost or floating.
