The 3-state outputs let you isolate multiple bus nodes on the same line, which is the usual need in an automotive ECU where a sensor interface, a gateway, and a body controller share a data bus. The 8 mA output drive (both high and low) is enough to fan out to four or five standard CMOS loads at 5 V, but if the downstream bus has a higher capacitive load or long trace, budget a buffer per signal group. The 3-state high-impedance state lets the output float, so multiple buffers can share a line without contention. ## Temperature range and automotive qualification The AEC-Q100 qualification means this part has passed the stress tests automotive OEMs require — temperature cycling, high-temperature operating life, and ESD robustness. For a BOM that needs a 5 V bus buffer in an engine control unit or transmission controller, this is the grade to specify. ## 14-TSSOP footprint — board-level fit The 0.65 mm pin pitch is standard for this family, and the package outline matches the industry-standard TSSOP-14 footprint. No special reflow profile beyond the usual lead-free solder process. ## Lifecycle and sourcing posture ROHS3 compliant.","metaTitle":"CAHCT126QPWRG4Q1 Buffer, Non-Inverting, 3-State, 14-TSSOP","metaDescription":"Texas Instruments CAHCT126QPWRG4Q1 automotive-grade buffer, non-inverting with 3-state outputs. 4.5V-5.5V supply, 8mA drive, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, 74AHCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Automotive, AEC-Q100, 74AHCT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"4","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"14-TSSOP","Current - Output High, Low":"8mA, 8mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.69000","currency":"USD"},{"qty":10,"price":"$0.60900","currency":"USD"},{"qty":25,"price":"$0.57160","currency":"USD"},{"qty":100,"price":"$0.46660","currency":"USD"},{"qty":250,"price":"$0.43344","currency":"USD"},{"qty":500,"price":"$0.36888","currency":"USD"},{"qty":1000,"price":"$0.29510","currency":"USD"},{"qty":2000,"price":"$0.26744","currency":"USD"},{"qty":6000,"price":"$0.26100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dccc412f8704fbc845633cbdd077b83b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CAHCT126QPWRG4Q1 a direct replacement for SN74AHCT126?","answer":"Verify pinout and electrical compatibility against your specific SN74AHCT126 variant before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CAHCT126QPWRG4Q1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CAHCT126QPWRG4Q1 when reusing this data.
