The 3-state outputs mean the buffer can be put into high-impedance mode when the enable pin is deasserted — critical for shared bus architectures where multiple devices share the same data lines and only one is allowed to drive at a time.","metaTitle":"SN74LS244N Buffer, Non-Inverting, 3-State, 20-DIP","metaDescription":"Texas Instruments SN74LS244N buffer, non-inverting with 3-state outputs, 4.75V–5.25V supply, 15mA/24mA drive, 20-DIP, active production, RoHS3.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74LS","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-PDIP","Current - Output High, Low":"15mA, 24mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.21000","currency":"USD"},{"qty":10,"price":"$1.07900","currency":"USD"},{"qty":25,"price":"$1.02400","currency":"USD"},{"qty":100,"price":"$0.84110","currency":"USD"},{"qty":250,"price":"$0.78624","currency":"USD"},{"qty":500,"price":"$0.69484","currency":"USD"},{"qty":1000,"price":"$0.54855","currency":"USD"},{"qty":2500,"price":"$0.51750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/074334bac5ff5b7cfbf08ab2c6ab03e9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy SN74LS244N and check current pricing?","answer":"Submit an RFQ for lot-specific pricing and lead time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS244N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS244N when reusing this data.
