ISO7310CQDQ1 General Description

The ISO7310-Q1 device provides galvanic isolation up to 3000 V_RMS for 1 minute per UL 1577 and 4242 V_PKper VDE V 0884-10. 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, the ISO7310-Q1 device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. The device has integrated noise filters for harsh industrial environment where short noise pulses may be present at the device input pins.

The ISO7310-Q1 device has TTL input thresholds and operate from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO7310-Q1 device has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.

For all available packages, see the orderable addendum at the end of the datasheet.
