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.
