ISO7421E - Low-Power Dual Channel Digital Isolators

This page provides the datasheet information for the ISO7421E, a member of the ISO7420E Low-Power Dual Channel Digital Isolators family.

Description

ISO742x provide galvanic isolation up to 2500 VRMS for 1 minute per UL and 4242 VPK per VDE.

These devices have two isolated channels.

Each channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier.
