Product Description
Product Overview
The CEU8420N1/CEU8420N0 series are high-speed, high-reliability dual-channel magnetic isolation general-purpose digital isolators, meeting a 3.0 kVRMS isolation withstand voltage according to UL-1577 standard. These isolators utilize chip-level microtransformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, balancing the timing precision of edge modulation with the robustness of On-Off Keying (OOK) modulation. The CEU8420N1/CEU8420N0 includes 2 forward signal channels and 0 reverse signal channels, with a typical signal transmission delay of less than 9 ns. They offer power-down protection: CEU8420N1 defaults to a high output level, and CEU8420N0 defaults to a low output level when input power is lost or floating.
