|---|---|---|---|---|
| FFF Compatibility | Shares the exact same DCT (SSOP-8) footprint and pinout assignments.Physically identical package dimensions and mounting style.Utilizes the exact same silicon die and electrical parameters (1.65 V to 5.5 V supply range). | Features identical pin assignments and 0.65 mm pitch, but physical package tolerances (TSSOP-8 / SOT505-2) differ slightly from the DCT package.The TSSOP-8 (DP) package has slightly different body dimensions (3.0 mm x 3.0 mm) compared to the SSOP-8 (2.8 mm x 2.8 mm) package.Offers identical multivibrator logic functionality and 1.65 V to 5.5 V voltage range compatibility. | ||
 AI Summary | SN74LVC1G123DCTT by Texas Instruments: Monostable Multivibrator 18.5 ns SM8. | This is the exact same component in the identical DCT (SM8/SSOP-8) package, differing only in the standard ordering quantity (3,000 pieces per reel instead of 250 for the DCTT suffix). It represents a 100% drop-in replacement.
| This is Nexperia's equivalent monostable multivibrator in a TSSOP-8 package. While it shares the same 0.65 mm pin pitch and pinout, the physical package envelope differs slightly and must be verified against the target PCB footprint.

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 Texas Instruments SN74LVC1G123DCTT is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
