Texas Instruments
Download the ISO7421FE datasheet PDF.
This datasheet also covers the ISO7420E variant, as both devices belong to the same low-power dual channel digital isolators family and are provided as variant models within a single manufacturer datasheet.
General 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.
Key Features
1 Signaling Rate > 50 Mbps.
Default Output 'High' and 'Low' Options.
Low Power Consumption: Typical ICC per Channel
(3.3-V Supplies):.
