3 Description

The ISO7310-Q1 device provides galvanic isolation

up to 3000 VRMS for 1 minute per UL 1577 and 4242

VPK per 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.
