ISO7310C - Robust EMC, Low Power, Single-Channel 1/0 Digital Isolator, Fail-Safe High

ISO7310x provide galvanic isolation up to 3000 V_RMS for 1 minute per UL and 4242 V_PK per VDE. These devices have one isolated channel comprised of a logic input and output buffer separated by a silicon dioxide (SiO₂) insulation barrier. Used in conjunction with isolated power supplies, ISO7310x prevent noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. These devices have integrated noise filters for harsh industrial environment where short noise pulses may be present at the device input pins. ISO7310x have TTL input thresholds and operate from 3 V to 5.5 V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of ISO7310x has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.
