| FFF Compatibility | The SSOP-48 footprint and pinout assignment are identical to the Fairchild 74ACT16240SSC, enabling a direct drop-in replacement on existing PCBs.The component uses the same SSOP-48 (also known as BSSOP-48) package with the same dimensions, lead pitch, and mounting type.The logical behavior, TTL-compatible inputs, propagation delays, supply voltage range (4.5V to 5.5V), and 24mA drive capabilities are identical. | The pinout and SSOP-48 footprint match the 74ACT16240SSC perfectly.The physical package is an identical SSOP-48 SMD design.Operates on the same 4.5V to 5.5V supply and performs the identical 16-bit inverting buffer function with improved drive currents. | ||
 AI Summary | 74ACT16240SSC by onsemi: Buffer, Inverting 4 Element 4 Bit per Element 3-State Output 48-SSOP. | This is a direct, active second-source equivalent from Texas Instruments. It shares the identical logic function, pinout, voltage ratings, and package size, making it a perfect drop-in replacement without any board layout or schematic changes.
| This part is a high-performance Advanced BiCMOS (ABT) family alternative. It operates at the same 5V logic supply and offers identical inverting buffer functionality with a stronger output drive capability, making it highly reliable for driving heavily loaded buses.

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 74ACT16240SSC 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 74ACT16240SSC are the 74ACT16240DLR (Texas Instruments) and the SN74ABT16240ADL (Texas Instruments), 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 74ACT16240SSC 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 74ACT16240SSC (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
