| FFF Compatibility | Features the identical SOIC-14 package (D package) with the exact same 14-pin assignment as the obsolete SN7406D.Utilizes the exact same 14-SOIC body size (3.90 mm width) and SMD mounting style.Performs the identical hex inverter function with identical electrical characteristics, including a 30V output breakdown voltage limit. | Features the identical 14-pin SOIC pinout assignment and footprint.Identical 14-SOIC package dimensions (3.90 mm width) and SMD mounting style.Performs the exact same open-collector hex inverter function with identical 30V/40mA maximum output ratings, but operates with lower power consumption. | ||
 AI Summary | SN7406D by Texas Instruments: Inverter IC 6 Channel Open Collector 14-SOIC. | The SN7406DR is the direct manufacturer-recommended substitute, differing only in the delivery packaging format (Tape & Reel instead of Tube). It is fully active and serves as a seamless, 100% drop-in replacement.
| The SN74LS06DR is an active Low-Power Schottky (LS) variant that is functionally and footprint compatible with the original standard TTL part. It provides the same 30V high-voltage open-collector capability while drawing significantly less supply current.

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 SN7406D 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 SN7406D are the SN7406DR (Texas Instruments) and the SN74LS06DR (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 SN7406D 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 SN7406D (Texas Instruments) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
