Product Description
Product Overview
The CEG1021 series is a dual-channel, magnetically isolated universal digital isolator that utilizes chip-level micro-transformers and proprietary modulation/demodulation technology for signal transmission. It features a widened isolation distance, enabling a withstand voltage exceeding 15 kVrms. The CEG1021 includes one inverting and one non-inverting signal channel, with typical signal transmission delays of approximately 0.8 s. In conditions of input power loss or floating input signal pins, the CEG1021 defaults to a high output level. Its applications include smart meters, industrial automation, home appliances, and isolated data buses.
