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 barriers.
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.For all available packages, see the orderable addendum at the end of the datasheet.
