Digital isolator coileasy CEU8720U1W with dual channel 5.7 kVRMS isolation and edge modulation timing precision
Product Overview
The CEU8720U1W/CEU8720U0W series are high-speed, high-reliability, dual-channel, wide-body digital isolators with 5.7 kVRMS isolation voltage capability under UL-1577 standard. Utilizing chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology, these isolators achieve signal transmission with the timing precision of edge modulation and the robustness of On-Off Keying (OOK) modulation. They feature 2 forward signal channels and 0 reverse signal channels, with a typical signal transmission delay of less than 9 ns. The series offers power-down protection, with CEU8720U1W defaulting to a high output level and CEU8720U0W to a low output level when input power is lost or floating.
