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.
