Introduction

The CEG1021 series is a dual-channel magnetically isolated general-purpose digital isolator. It utilizes chip-scale micro-transformers and proprietary modulation/demodulation technology for signal transmission, featuring widened isolation spacing to achieve a withstand voltage of greater than 15 kVrms. The CEG1021 contains 1 reverse signal channel and 1 forward signal channel, both with a typical signal propagation delay of approximately 0.8 μs. When the input power supply is lost or the input signal pins are floating, the CEG1021 default output level is high.

Features

• Data rate: 0–150 kbps
• Low power consumption: 0.7 mA @ 3.3 V/channel
