ISO733x Robust EMC, Low Power, Triple-Channel Digital Isolators

1 Features

3 Description

ISO733x provide galvanic isolation up to 3000 V_RMS

•

Signaling Rate: 25 Mbps

for 1 minute per UL and 4242 V_PKper 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

device input pins. ISO733x 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 ISO733x

has been significantly enhanced to enable system-

level ESD, EFT, Surge and Emissions compliance.
