High speed dual channel digital isolator coileasy CEU8422N0 with magnetic isolation and low transmission delay
Product Overview
The CEU8422N1/CEU8422N0 series are high-speed, high-reliability, dual-channel, magnetically isolated universal digital isolators. They meet a 3.0 kVRMS isolation withstand voltage according to UL-1577 standard. Utilizing chip-scale micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, they balance timing accuracy of edge modulation with robustness of On-Off Keying (OOK) modulation. The devices feature one forward and one reverse signal channel with a typical signal transmission delay of less than 9 ns. Both CEU8422N1 and CEU8422N0 offer power-down protection, with CEU8422N1 defaulting to a high output level and CEU8422N0 to a low output level when input power is lost or floating.
