SLLSEK9B – JANUARY 2015 – REVISED APRIL 2015 ISO733x Robust EMC, Low Power, Triple-Channel Digital Isolators
1 Features 3 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 …
