It takes four independent AND gates, each with two inputs, and drives standard TTL loads. The 74S family uses Schottky clamping to reduce propagation delay — this part delivers 7.5 ns typical at 5 V into 50 pF, which keeps it fast enough for bus decoding, control signal gating, and address latching in 5 V digital systems. Supply range is 4.75 V to 5.25 V, the classic 5 V TTL rail. Outputs source 1 mA and sink 20 mA, enough to drive one or two standard TTL loads per gate. Operating temperature is 0°C to 70°C, so it fits indoor equipment, office gear, and benchtop instruments — not engine bays or outdoor cabinets. ## 7.5 ns propagation delay — timing margin in fast glue Maximum propagation delay is 7.5 ns at 5 V and 50 pF load. ## Active production — no LTB watch needed The SN74S08D is listed as Active in production. No last-time-buy or end-of-life notice is on record.","metaTitle":"SN74S08D 74S Quad 2-Input AND Gate, 7.5ns, SOIC-14","metaDescription":"SN74S08D from TI: 74S series quad 2-input AND gate, 4.75V–5.25V supply, 7.5ns propagation delay, 14-SOIC.

Both are quad 2-input AND gates in the same SOIC-14 footprint and share the same 5 V supply rail, but the S version has a 7.5 ns delay versus roughly 15 ns for the LS. If the LS08 was marginal on timing, the S08 will improve margin; if the LS08 was fine, the S08 works as a drop-in replacement electrically and mechanically."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74S08D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74S08D when reusing this data.
