High speed three channel digital isolator coileasy CEU8731U0W with consumption and selectable default output levels
Product Overview
The CEU8731U1W/CEU8731U0W is a high-speed, high-reliability, three-channel digital isolator with 5.7 kVrms isolation voltage, housed in a wide-body SOW-16 package. It utilizes chip-scale micro-transformers and proprietary AdaptivePulse modulation/demodulation technology for signal transmission, offering a balance between edge-modulated timing precision and OOK robustness. With a typical signal transmission delay of less than 10 ns and common-mode transient immunity of 200 kV/s, it features 2 forward and 1 reverse signal channels. The device includes a power-down protection function, allowing for selectable default output levels upon input power loss.
