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.
