| FFF Compatibility | Identical TSSOP-20 (PW) package and pin assignments, including the complementary active-low/active-high output enables on pins 1 and 19.Standard TSSOP-20 package dimensions (6.5mm x 4.4mm body) match the target.Shares the exact same 74ACT logic subfamily, 4.5V to 5.5V supply voltage range, high-speed performance, and 24mA sink/source output drive. | Uses the exact same TSSOP-20 package and pin assignments.Identical TSSOP-20 outline and footprint dimensions.Belongs to the slower HCT logic family instead of the high-speed ACT family. It has lower output current drive (6mA vs 24mA) and slower propagation delays. | ||
 AI Summary | MC74ACT241DT by onsemi: Element Bit per Element Output. | This is the primary drop-in replacement for the obsolete MC74ACT241DT. It matches the exact logic family, speed characteristics, and 24mA output drive strength of the original onsemi part.
| This is a same-manufacturer alternative belonging to the HCT logic subfamily. While it serves as a physical drop-in, it trades off performance with lower output drive capability (6mA vs 24mA) and slower propagation times.

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 MC74ACT241DT 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 MC74ACT241DT are the SN74ACT241PWR (Texas Instruments) and the MC74HCT241ADTR2G (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 MC74ACT241DT 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 MC74ACT241DT (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
