3 Description
The ISO732x-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 two isolated channels comprised of logic input
and output buffers separated by silicon dioxide (SiO2)
insulation barriers.
The ISO7320-Q1 has both channels in the same
direction while ISO7321-Q1 has the two channels in
opposite 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 Device Functional
Modes for more information. 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 ISO732x-Q1 family of devices
has integrated noise filters for harsh industrial
environment where short noise pulses may be
present at the device input pins. The ISO732x-Q1
family of devices has TTL input thresholds and
operate from 3-V to 5.5-V supply levels.
Through innovative chip design and layout
techniques, electromagnetic compatibility of the
ISO732x-Q1 family of devices has been significantly
enhanced to enable system-level ESD, EFT, Surge
and Emissions compliance.
