Alternatives to Texas Instruments SN74LV123ADR
Texas Instruments SN74LV123ADR and its qualified second sources, compared on form/fit/function, stock, lifecycle and price — the same checks Parter runs inside a BOM.
 SN74LV123ADRTexas Instruments |  74LV123D,118Nexperia USA Inc. |  74VHC123AMXonsemi | +1more | |
|---|---|---|---|---|
| FFF Compatibility | Uses the same 16-pin SOIC (D) package with identical pinout assignments verified from the datasheet.Matches the exact physical dimensions and package width (3.90 mm / 0.154 inch) for immediate land pattern compatibility.Functions as a dual retriggerable monostable multivibrator with identical 12mA output drive and electrical properties. | Pinout structure is identical to the original SN74LV123ADR standard pin configuration.Uses the standard 16-SOIC package with 0.154 inch width matching the original footprint.Operating temperature range is narrower (-40°C to 85°C vs -40°C to 125°C) and output drive current is lower (8mA vs 12mA). | ||
 AI Summary | SN74LV123ADR by Texas Instruments: Monostable Multivibrator 13 ns 16-SOIC. | This is a high-confidence, second-source alternative from Nexperia that serves as a direct drop-in replacement. It maintains complete parity in safety limits, pinout structure, and logic characteristics.
| This onsemi device is a highly compatible alternative from the 74VHC family, sharing the same physical footprint and pin layout. It is restricted to standard commercial/industrial temperatures and has slightly lower output current capacity.

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 SN74LV123ADR is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Texas Instruments SN74LV123ADR are the 74LV123D,118 (Nexperia USA Inc.) and the 74VHC123AMX (onsemi), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
