Its supply range from 0.8V to 3.6V means this single part can buffer signals on 1.2V, 1.8V, 2.5V, or 3.3V rails without needing a level translator at the input — handy for mixed-voltage designs where a sensor output at 1.8V feeds a 3.3V logic input. Each output can source or sink 4mA, enough to drive a single CMOS load or a short LED indicator. The -40°C to 85°C operating range covers most industrial and outdoor telecom enclosures. ## Schmitt-trigger input — why it matters for real-world signals The Schmitt-trigger input provides hysteresis, which means it won't oscillate or produce false edges when the incoming signal is noisy or has a slow rise time. That's the difference between a clean pushbutton debounce and a glitchy counter. If your design routes a long PCB trace from a sensor or a mechanical switch, this buffer cleans up the edge before it hits the downstream logic. ## SC-70-6 footprint — board-area reality The SC-70-6 (also known as SOT-363) package is tiny — roughly 2.0 mm × 1.25 mm — which saves real estate on dense PCBs. Surface-mount only, so hand-prototyping requires a fine-tip iron or hot-air rework. The supply voltage tolerance down to 0.8V means decoupling is less critical than with older 5V logic, but a 0.1 µF ceramic right at the pin is still good practice. ## Active lifecycle — no LTB pressure There is no last-time-buy notice or obsolescence risk on the horizon. For new designs this is a safe selection; for existing BOMs it means no urgent re-qualification needed.","metaTitle":"SN74AUP2G17DCKR 74AUP Dual Buffer, Schmitt-Trigger","metaDescription":"SN74AUP2G17DCKR from TI's 74AUP series: dual non-inverting buffer with Schmitt-trigger inputs, 0.8V to 3.6V supply, 4mA output drive, -40°C to 85°C, SC-70-6.","metaKeywords":null},"attributes":{"series":"74AUP","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74AUP","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"Schmitt Trigger","Logic Type":"Buffer, Non-Inverting","Output Type":"Push-Pull","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.6V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SC-70-6","Current - Output High, Low":"4mA, 4mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.55","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.55000","currency":"USD"},{"qty":10,"price":"$0.47300","currency":"USD"},{"qty":25,"price":"$0.44160","currency":"USD"},{"qty":100,"price":"$0.35320","currency":"USD"},{"qty":250,"price":"$0.32796","currency":"USD"},{"qty":500,"price":"$0.27750","currency":"USD"},{"qty":1000,"price":"$0.21444","currency":"USD"},{"qty":3000,"price":"$0.19552","currency":"USD"},{"qty":6000,"price":"$0.18290","currency":"USD"},{"qty":15000,"price":"$0.17850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7d37ad2bd55211bb995a8718f1d070a1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the SN74AUP2G17DCKR work at 3.3V?","answer":"Yes. The supply range is 0.8V to 3.6V, so 3.3V is well within the operating window. The Schmitt-trigger inputs accept 3.3V logic levels directly."},{"question":"Is the SN74AUP2G17DCKR suitable for 1.8V systems?","answer":"Yes. The 0.8V to 3.6V supply covers 1.8V rails. The buffer will operate correctly at 1.8V and the Schmitt-trigger inputs will still provide hysteresis."},{"question":"What is the difference between SN74AUP2G17DCKR and SN74AUP2G17DCTR?","answer":"Both parts share the same die and electrical specs. The difference is packaging and tape/reel format. The DCKR suffix indicates SC-70-6 in Tape & Reel; the DCTR suffix is typically SSOP-8. Check the specific package drawing for footprint compatibility."},{"question":"What is a direct replacement for SN74AUP2G17DCKR?","answer":"A pin-compatible functional equivalent is the SN74LVC2G17QDCKRQ1 (automotive-grade, AEC-Q100, wider temp range -40°C to 125°C).
