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 low for orderable part numbers with suffix F and high for orderable part numbers without suffix F. See Device Functional Modes 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.
