| FFF Compatibility | TSSOP-20 package dimensions and JEDEC standard pin assignment match perfectly.Direct physical replacement with the same surface mount TSSOP footprint.Matches or exceeds all original electrical specs, including bus-hold, 3-state output, and high-drive current. | Standard TSSOP-20 package with the exact same layout and pinout arrangement.Identical package dimensions allow it to be soldered to the existing board layout.Belongs to the 74LVT family which lacks the input bus-hold ('H') feature of the original 74LVTH part. | ||
 AI Summary | 74LVTH244MTCX by onsemi: Buffer, Non-Inverting 2 Element 4 Bit per Element 3-State Output 20-TSSOP. | The SN74LVTH244APWR from Texas Instruments is an active, highly reliable direct replacement. It maintains the identical low-voltage BiCMOS technology with bus-hold capability, matching all critical safety, timing, and drive parameters of the obsolete Fairchild part. No board or circuit redesign is needed.
| This active alternative matches the package and the high-drive performance of the original device. However, because it belongs to the standard 74LVT family, it lacks the internal bus-hold circuitry. If your application leaves input lines floating, you will need to add external pull-up or pull-down resistors.

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 74LVTH244MTCX 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 74LVTH244MTCX are the SN74LVTH244APWR (Texas Instruments) and the 74LVT244APW,118 (Nexperia), 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 74LVTH244MTCX 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 74LVTH244MTCX (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
