SLLSEK8C – JANUARY 2015 – REVISED APRIL 2015 ISO732x Robust EMC, Low Power, Dual-Channel Digital Isolators
1 Features 3 Description 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 …
