Description

ISO733x provide galvanic isolation up to 3000 VRMS for 1 minute per UL and 4242 VPK per VDE. These devices have three isolated channels comprised of logic input and output buffers separated by a silicon dioxide (SiO2) insulation barrier. ISO7330 has all three channels in the same direction while ISO7331 has two channels in forward and one channel in reverse 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’. 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. ISO733x has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. ISO733x has TTL input thresholds and operates from 3 V to 5.5 V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of ISO733x has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.
