•

Signaling Rate: 25 Mbps

•

Integrated Noise Filter on the Inputs

devices have three isolated channels comprised of

•

Default Output 'High' and 'Low' Options

logic input and output buffers separated by a silicon

•

three channels in the same direction while ISO7331

at 1 Mbps:

has two channels in forward and one channel in

ISO7330: 1 mA (5 V Supplies),

reverse direction. In case of input power or signal

0.8 mA (3.3 V Supplies)

loss, default output is 'low' for devices with suffix 'F'

–

ISO7331: 1.4 mA (5 V Supplies),

and 'high' for devices without suffix 'F'. Used in

conjunction with isolated power supplies, these

1 mA (3.3 V Supplies)

devices prevent noise currents on a data bus or other

with or damaging sensitive circuitry. ISO733x has

•

Operates from 3.3 V and 5 V Supplies

integrated noise filter for harsh industrial environment

•

3.3 V and 5 V Level Translation

where short noise pulses may be present at the

device input pins. ISO733x has TTL input thresholds

•

Wide Temperature Range: –40°C to 125°C

and operates from 3 V to 5.5 V supply levels.
