That means Texas Instruments has stopped production, and no last-time-buy window remains open. For a new design, this part is not an option. For an existing BOM, you are looking at the surplus and broker channel to fill the line.
Package and footprint — SOT-23-5
The part comes in a 5-lead SOT-23-5 package, also described as SC-74A. The small footprint (roughly 2.9 mm × 1.6 mm) suits dense layouts.
