It is a standard 74ALS-series part, so it mates directly with 5 V TTL and other ALS/AS logic families on the same backplane. The 14 ns propagation delay at 5 V, 50 pF sets the timing closure window for address decoding, strobe generation, or any combinatorial glue logic where a clean AND function is needed without the faster (but higher-power) 74F or 74AC alternatives. ## Output drive and input thresholds Each gate sinks 8 mA and sources 400 µA. The 8 mA sink handles multiple standard TTL loads or a single low-current LED with a series resistor; the 400 µA source is typical for driving CMOS inputs or high-impedance bus receivers. Input low threshold is 0.8 V, high threshold is 2 V — standard 5 V TTL-compatible levels that guarantee noise margin against a 5 V rail. ## Temperature grade and environment Rated for 0°C to 70°C commercial temperature range. This suits indoor equipment, benchtop instrumentation, telecom line cards in conditioned racks, and general-purpose industrial control panels where the ambient stays within that band. Not specified for automotive or extended industrial environments. ## Sourcing and lifecycle The SN74ALS08D carries an active lifecycle status and is ROHS3 compliant. No last-time-buy pressure on this line.","metaTitle":"SN74ALS08D 74ALS Quad 2-Input AND Gate, 14 ns @ 5V","metaDescription":"TI SN74ALS08D quad 2-input AND gate in 14-SOIC. 4.5V-5.5V supply, 8 mA sink, 14 ns prop delay.","metaKeywords":null},"attributes":{"series":"74ALS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ALS","Package":"Tube","Logic Type":"AND Gate","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"4.5V ~ 5.5V","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C","Input Logic Level - Low":"0.8V","Supplier Device Package":"14-SOIC","Input Logic Level - High":"2V","Current - Output High, Low":"400µA, 8mA","Max Propagation Delay @ V, Max CL":"14ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.93","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.93000","currency":"USD"},{"qty":10,"price":"$0.83200","currency":"USD"},{"qty":25,"price":"$0.78960","currency":"USD"},{"qty":100,"price":"$0.64850","currency":"USD"},{"qty":250,"price":"$0.60620","currency":"USD"},{"qty":500,"price":"$0.53572","currency":"USD"},{"qty":1000,"price":"$0.42294","currency":"USD"},{"qty":2500,"price":"$0.39900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4047b02af33efdc389e6951412b06513.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of SN74ALS08D?","answer":"The maximum propagation delay is 14 ns at 5 V supply with a 50 pF load. That figure governs the timing budget for address decoding or clock gating in a 5 V bus — it is fast enough for most 8-bit and 16-bit systems but slower than the 5 ns of a 74F00 NAND gate."},{"question":"Is SN74ALS08D compatible with 5V logic?","answer":"Yes, it operates on a 4.5 V to 5.5 V supply with TTL-compatible input thresholds (0.8 V low, 2 V high) and standard ALS output levels. It interfaces directly with 5 V TTL, ALS, AS, and HC logic families without level translation."},{"question":"What is the equivalent of SN74ALS08D?","answer":"A functional equivalent in the same 74ALS family is the SN74ALS11ANS, which is a triple 3-input AND gate in a similar 14-pin surface-mount package. The SN74ALS08D is a quad 2-input gate; the SN74ALS11ANS is a triple 3-input gate — the logic function differs, so they are not pin-compatible drop-in replacements. For a faster quad 2-input NAND gate, the SN74F00DR offers 5 ns propagation delay but draws higher supply current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALS08D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALS08D when reusing this data.
