3 Description
The ISO733x-Q1 family of devices provides galvanic
isolation up to 3000 VRMS for 1 minute per UL 1577 and 4242 VPK per VDE V 0884-10. These devices
have three isolated channels comprised of logic input
and output buffers separated by a silicon dioxide
(SiO2) insulation barrier.
The ISO7330-Q1 has all three channels in the same
direction while ISO7331-Q1 has two channels in forward and one channel in reverse direction. In case
of input power or signal loss, the default output is low
for orderable part numbers with suffix F and high for
orderable part numbers without suffix F. See the
Device Functional Modes section 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. The ISO733x-Q1 family of devices has integrated noise
filter for harsh industrial environment where short
noise pulses may be present at the device input pins.
The ISO733x-Q1 family of devices 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 the
ISO733x-Q1 family of devices has been significantly
enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.
