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.
