3 Description

The ISO734x-Q1 family of devices provides galvanic isolation up to 3000 V_RMS for 1 minute per UL 1577 and 4242 V_PK 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.

Simplified Schematic

V_CCI and GNDI are supply and ground connections respectively for the input channels.

V_CCO and GNDO are supply and ground connections respectively for the output.
