| FFF Compatibility | Both parts use the exact same SOIC-20 (0.295\" width) package and share identical pinout assignments for OE, LE, and data lines.Both devices are packaged in standard 20-SOIC footprints with identical physical dimensions and mounting specifications.Electrical performance parameters, including operating voltage, output current capacity (24mA), and propagation delays, are completely identical. | Features the identical 20-SOIC (DW) package with the same pin assignment mapping.Identical physical dimensions and land pattern requirements.Operates as a high-speed TTL-compatible CMOS octal latch with identical 24mA output drive and 4.5V to 5.5V supply limits. | ||
 AI Summary | MC74ACT573DWR2 by onsemi: D-Type Transparent Latch 1 Channel 1:8 IC Tri-State 20-SOIC. | This is the direct Pb-free and RoHS-compliant drop-in replacement for the obsolete MC74ACT573DWR2 from the exact same manufacturer and product series. It offers fully identical electrical characteristics, propagation delays, and pinout configuration.
| The SN74ACT573DWR from Texas Instruments is an active, highly compatible second-source alternative. It operates with the same logic configuration, output drive, and package constraints while providing slightly faster propagation times.

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.
Frequently asked questions
Yes. The onsemi MC74ACT573DWR2 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the onsemi MC74ACT573DWR2 are the MC74ACT573DWR2G (onsemi) and the SN74ACT573DWR (Texas Instruments), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the MC74ACT573DWR2 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The MC74ACT573DWR2 (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
