| FFF Compatibility | Identical TSSOP-20 package layout and pin-to-pin assignments verified via datasheet analysis.Identical physical package dimensions and surface-mount style (TSSOP-20, 4.4mm width).Matches all primary electrical specs including voltage supply range, drive currents, and speed. | Identical TSSOP-20 package layout and pin-to-pin assignments.Identical physical package dimensions (TSSOP-20, 4.4mm width).Features active bus-hold circuitry (LVTH) on the inputs, which might interact with specific pulldown or weak analog driver configurations on the bus. | ||
 AI Summary | 74LVT574MTCX by onsemi: Flip Flop 1 Element D-Type 8 Bit Positive Edge 20-TSSOP (0.173", 4.40mm Width). | This is the primary direct drop-in replacement. It belongs to the same standard LVT BiCMOS logic family (without bus-hold), meaning it matches all physical, mechanical, and electrical specifications of the obsolete onsemi part.
| This is the bus-hold (LVTH) version of the 574 flip-flop from Texas Instruments. It is fully pin-compatible and matches physical dimensions and output drive ratings, but includes active input-holding circuitry that keeps floating inputs at their last valid logic state.

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 74LVT574MTCX 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 74LVT574MTCX are the SN74LVT574PWR (Texas Instruments) and the SN74LVTH574PWR (Texas Instruments), 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 74LVT574MTCX 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 74LVT574MTCX (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
