Dual channel magnetic isolation digital isolator coileasy CEU8721N0 with less than 9 nanoseconds typical delay
Product Overview
The CEU8721N1/CEU8721N0 series are high-speed, high-reliability dual-channel magnetic isolation universal digital isolators, meeting a 3.0 kVRMS isolation withstand voltage under UL-1577 standard. Utilizing chip-level microtransformers 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 isolators feature one inverting and one non-inverting signal channel with a typical signal transmission delay of less than 9 ns. The series offers power-down protection, with CEU8721N1 defaulting to a high output level and CEU8721N0 to a low output level when input power is lost or floating.
