High speed dual channel digital isolator coileasy CEU8422N1 with consumption and power down protection
Product Overview
The CEU8422N1/CEU8422N0 series are high-speed, high-reliability dual-channel magnetically isolated universal digital isolators, meeting UL-1577 standard with 3.0 kVRMS isolation withstand voltage. They utilize chip-level micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, balancing edge modulation's timing accuracy with OOK modulation's robustness. Featuring one forward and one reverse signal channel, they offer a typical signal transmission delay of less than 9 ns. The series provides 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.
