ISO7421 - Low-Power Dual-Channel Digital Isolators
Texas Instruments
Download the ISO7421 datasheet PDF.
This datasheet also covers the ISO7420 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
The ISO7420, ISO7420M and ISO7421 provide galvanic isolation up to 2500 VRMS for 1 minute per UL.
These digital isolators have two isolated channels.
Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier.

Low Power Consumption, Typical ICC per Channel
(3.3-V operation):.
ISO7420: 1.1 mA, ISO7421: 1.5 mA.
Low Propagation Delay.
9 ns Typical.
Low Skew.
300 ps Typical.
Wide TA Range:.
40°C to 125°C (M-Grade).
50-kV/μs Transient Immunity, Typical.
Over 25-Year Isolation Integrity at Rated Voltage.
Operates From 3.3-V and 5-V Supply and Logic Levels.
