| FFF Compatibility | Shares the exact same 48-TSSOP package and pin configuration as the original part.Physical package dimensions, landing pattern, and pin count are identical.Utilizes the same internal silicon and electrical characteristics, offering a true drop-in functional replacement. | Uses a 38-pin TSSOP package instead of the original 48-pin TSSOP package, requiring a board redesign.Both are surface-mount TSSOP packages, but they have different pin counts (38 pins vs 48 pins) and body dimensions.Functions strictly as an LVTTL-to-LVDS transmitter/driver rather than an LVDS-to-LVDS repeater, and operates at a lower maximum data rate of 630 Mbps. | ||
 AI Summary | FIN1108MTD by onsemi: Buffer, ReDriver 8 Channel 800Mbps 48-TSSOP. | This is the direct sibling variant of the obsolete FIN1108MTD, differing only in the packaging method. It remains active, in production, and widely available.
| An alternative option if your application only requires driving LVDS signals from TTL/CMOS source logic on the same board, though it requires a footprint redesign.

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 FIN1108MTD 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 FIN1108MTD are the FIN1108MTDX (onsemi) and the SN65LVDS389DBT (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 FIN1108MTD 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 FIN1108MTD (onsemi) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
