The ISO732x-Q1 family of devices provides galvanic
isolation up to 3000 VRMS for 1 minute per UL 1577 and 4242 VPK
per VDE V 0884-10. These devices have two isolated channels comprised of logic input
and output buffers separated by silicon dioxide (SiO2) insulation
The ISO7320-Q1 has both channels in the same direction
while ISO7321-Q1 has the two channels in opposite direction.
In case of input power or signal loss,
the default output is for orderable part numbers with suffix
and for orderable part
numbers without suffix . See for more information. Used in conjunction with isolated
power supplies, these devices prevent noise currents on a data bus or other circuits from entering
the local ground and interfering with or damaging sensitive circuitry. The ISO732x-Q1 family of devices has integrated noise filters for harsh industrial
environment where short noise pulses may be present at the device input pins. The ISO732x-Q1 family of devices 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 ISO732x-Q1 family of devices has been significantly enhanced to
enable system-level ESD, EFT, Surge and Emissions compliance.
