3 Description

ISO7310x provide galvanic isolation up to 3000 VRMS

for 1 minute per UL and 4242 VPK 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.
