ISO732x provide galvanic isolation up to 3000 VRMS for 1 minute per UL and 4242 VPK per VDE. These devices have two isolated channels comprised of logic input and output buffers separated by silicon dioxide (SiO2) insulation barriers. ISO7320 has both channels in the same direction while ISO7321 has the two channels in opposite direction. In case of input power or signal loss, default output is ‘low’ for devices with suffix ‘F’ and ‘high’ for devices without suffix ‘F’. See Device Functional Modes for further details. 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. ISO732x have integrated noise filters for harsh industrial environment where short noise pulses may be present at the device input pins. ISO732x 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 ISO732x have been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.
