3 Description

The ISO734x-Q1 family of devices provides galvanic

have four isolated channels comprised of logic input

and output buffers separated by a silicon dioxide

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.
