3 Description
The ISO734x-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 four isolated channels comprised of logic input
and output buffers separated by a silicon dioxide
(SiO2) insulation barrier.
The ISO7340-Q1 device has four channels in forward
direction, the ISO7341-Q1 device has three forward
and one reverse-direction channels, and the
ISO7342-Q1 device has two forward and two reverse-
direction channels. 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.
