| FFF Compatibility | The package is an 8-SOIC narrow footprint with an identical pinout configuration.Same 8-SOIC package dimensions (3.90 mm width) and SMD mounting style.Fully compatible unidirectional 2/0 channel direction, fail-safe output-high behavior, and wider voltage supply support. | Same silicon family, package type, and pinout assignments.Matches the 8-SOIC physical dimensions exactly.Maintains the same 2/0 unidirectional channel direction, default-high fail-safe mode, and general-purpose isolation technology. | ||
 AI Summary | ISO7220ADR by Texas Instruments: General Purpose Digital Isolator 2500Vrms 2 Channel 1Mbps 25kV/µs CMTI 8-SOIC (0.154", 3.90mm Width). | The ISO7720DR is Texas Instruments' recommended newer-generation upgrade for the ISO7220 series. It offers a drop-in layout compatibility, identical logic default-high behavior, and vastly improved signal speed and noise immunity ratings.
| The ISO7220CDR is a direct drop-in speed upgrade from the same product family. It shares identical pinouts, footprint, and default-high fail-safe state, but supports up to 25 Mbps data rates and shorter propagation delays.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
