The device uses TI's silicon dioxide (SiO2) capacitive isolation barrier providing 2500Vrms isolation per UL 1577 and 4000Vpk basic insulation per VDE 0884-10. With 25kV\/\u03bcs minimum CMTI, 19ns typical propagation delay, and 2ns max pulse width distortion, it is designed for high-speed digital isolation in industrial and communications systems. Each side can be powered independently from 3.15V to 5.5V.","working_principle":"The ISO7240MDWR uses capacitive coupling through a silicon dioxide (SiO2) isolation barrier to transmit digital signals across the isolation boundary. The input signal modulates a high-frequency carrier that is capacitively coupled across the isolation barrier, then demodulated and reconstructed on the output side. The M suffix denotes CMOS input thresholds at VCC\/2 without the input noise filter found in the C (TTL) version, enabling higher data rates up to 150Mbps at the cost of reduced noise filtering. The 25kV\/\u03bcs CMTI ensures the output remains stable during fast common-mode transients typical of motor drive and power converter environments. The double-sided isolation architecture provides symmetrical performance regardless of signal direction.","pin_description":"
