ISO7321CDR

The ISO7321CDR is a dual-channel Digital Isolator provides galvanic isolation up to 3000VRMS for 1 minute per UL and 4242 VPK per VDE. It has two isolated channels comprised of logic input and output buffers separated by silicon dioxide (SiO2) insulation barriers. The ISO7320 has both channels in the same direction. It prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. It has integrated noise filters for harsh industrial environment where short noise pulses may be present at the device input pins. It has TTL input thresholds and operate from 3 to 5.5V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of ISO732x has been significantly enhanced to enable system-level ESD, EFT, surge and emissions compliance.
