|---|---|---|---|---|
| FFF Compatibility | The physical pinout and footprint matches the SN74HC14PWT exactly, using the standard TSSOP-14 package with identical pin assignments.The physical package type is a 14-TSSOP (PW package) with identical dimensions (0.173 inches / 4.40mm width).The electrical parameters, logic thresholds, and timing specifications are fully identical. The only difference is the standard large Tape & Reel packaging (PWR) vs small/partial Tape & Reel (PWT). | The pin assignments and physical footprint match the original TSSOP-14 package.The dimensions are a standard 14-TSSOP package with 4.40mm width.This device meets or exceeds all electrical performance parameters of the original TI part. | ||
 AI Summary | SN74HC14PWT by Texas Instruments: Inverter IC 6 Channel Schmitt Trigger 14-TSSOP. | The SN74HC14PWR is the direct, active drop-in replacement from Texas Instruments. It shares the same datasheet, package, pinout, and electrical characteristics as the obsolete SN74HC14PWT, differing only in the tape-and-reel delivery package size.
| The MC74HC14ADTR2G is a high-quality alternative from onsemi that offers an extended temperature rating and slightly faster switching speeds. It is an active, widely available second-source part that fits the same PCB footprint without any design changes.

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 SN74HC14PWT 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 Texas Instruments SN74HC14PWT are the SN74HC14PWR (Texas Instruments) and the MC74HC14ADTR2G (onsemi), out of 4 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 SN74HC14PWT 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 SN74HC14PWT (Texas Instruments) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
