3 Description
The ISO7310-Q1 device provides galvanic isolation
up to 3000 V_RMS for 1 minute per UL 1577 and 4242
V_PK 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.
