3 Description

The ISO734x 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 four isolated channels comprised of logic input

and output buffers separated by a silicon dioxide

(SiO2) insulation barrier.

The ISO7340x device has four channels in forward

direction, the ISO7341x device has three forward and

one reverse-direction channels, and the ISO7342x

device has two forward and two reverse-direction

channels. In case of input power or signal loss, the

default output is low for devices with suffix F and high

for devices without suffix F. See the Device

Functional Modes section for further details.
