Texas Instruments lists the part as active in production, so it remains a viable BOM line for designs that still specify LS logic — no last-time-buy scramble yet. ## Package, compliance, and sourcing reality Supplied in Bulk — loose units, not tape-and-reel, which is typical for through-hole or large-pin-count DIPs that don't feed into pick-and-place without tube or tray. RoHS non-compliant — the lead finish is likely tin-lead, which is a showstopper for EU RoHS lines but still accepted in military, aerospace, and some industrial builds that have exemptions or legacy BOMs.","metaTitle":"DM54LS193J/883 Texas Instruments Binary Counter, LS Series","metaDescription":"DM54LS193J/883 Texas Instruments LS series synchronous 4-bit up/down binary counter.
