High speed dual channel digital isolator coileasy CEU8421N0 with 3 kilovolt rms isolation and consumption
Product Description
The CEU8421N1/CEU8421N0 series are high-speed, high-reliability dual-channel magnetically isolated universal digital isolators, meeting UL-1577 standard with 3.0 kVRMS isolation withstand voltage. Utilizing chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, they balance the timing accuracy of edge modulation with the robustness of On-Off Keying (OOK) modulation. The series includes one inverting signal channel and one non-inverting signal channel, with a typical signal transmission delay of less than 9 ns. These isolators offer power-down protection: CEU8421N1 defaults to a high output level, and CEU8421N0 defaults to a low output level when input power is lost or floating.
