communication isolator HopeRF Micro-electronics CMT8120N0 with low radiation and high EMC immunity features
Product Overview
The CMT812X is a high-performance, dual-channel digital isolator utilizing silicon dioxide (SiO2) insulation technology, offering up to 5 kVrms isolation voltage. It facilitates communication between two different power domains, preventing noise currents from affecting sensitive local ground or circuits. The CMT812X series features enhanced electromagnetic compatibility (EMC) with system-level ESD, EFT, and surge immunity, alongside low radiation. Available in SOIC-16 (wide body), SOW8L (wide body), and SOIC-8 (narrow body) packages, it supports data rates from DC to 150 Mbps across a wide supply voltage range of 2.5 V to 5.5 V and an operating temperature range of -40C to 125C.
