Each element handles a single bit, and the 3-state outputs let you share a bus line without contention — the output goes high-impedance when the enable pin is deasserted. Supply voltage spans 0.8 V to 3.6 V, covering 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic rails. This makes it a natural fit for mixed-voltage designs where a single buffer must cross between a low-voltage core and a higher-voltage peripheral bus — no external level translator needed as long as the input thresholds align. Output drive is rated 4 mA source and 4 mA sink at the rated supply. That is enough to drive a single CMOS load or a short trace on a PCB; for heavier fan-out or long backplane runs, plan on a buffer with higher drive (like the 74LVC family's 24 mA or 32 mA options). ## Industrial temperature range and package fit Operating temperature covers -40°C to 85°C (TA), which is the industrial grade. The part is specified across this full range — the 4 mA output current and propagation delays are guaranteed at the extremes, not just at 25°C. For an outdoor telecom or factory-floor controller that sees -20°C startup and 70°C internal ambient, this buffer holds its timing margins. Packaged in 8-VFSOP (2.30 mm width) with the supplier device package listed as 8-VSSOP. The two names refer to the same footprint — TI's very-thin shrink small-outline package. The 0.5 mm pin pitch and 2.3 mm body width fit into tight PCB layouts where board area is at a premium. Surface-mount only; no through-hole variant exists. ## Lifecycle and sourcing status Sourced to order against BOM quantities. No single-source risk — the 74AUP family is widely second-sourced by multiple logic vendors, though this exact order code is TI-specific.","metaTitle":"SN74AUP2G126DCUR Buffer Non-Inverting 3-State, 0.8-3.6V","metaDescription":"Texas Instruments SN74AUP2G126DCUR dual buffer, non-inverting with 3-state outputs. 4mA drive, 0.8V-3.6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74AUP","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"74AUP","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"8-VFSOP (0.091\\\", 2.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.6V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-VSSOP","Current - Output High, Low":"4mA, 4mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.75","priceTiers":[{"qty":1,"price":"$0.75000","currency":"USD"},{"qty":10,"price":"$0.66100","currency":"USD"},{"qty":25,"price":"$0.62120","currency":"USD"},{"qty":100,"price":"$0.50690","currency":"USD"},{"qty":250,"price":"$0.47080","currency":"USD"},{"qty":500,"price":"$0.40068","currency":"USD"},{"qty":1000,"price":"$0.32054","currency":"USD"},{"qty":3000,"price":"$0.29049","currency":"USD"},{"qty":6000,"price":"$0.28350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2f2cf8fa72578c3a10ebf0238e037af5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74AUP2G126DCUR/alternatives.json"},"ai":{"faq":[{"question":"Is the SN74AUP2G126DCUR a direct drop-in replacement for the SN74LVTH16245ADGVR?","answer":"No. The SN74LVTH16245ADGVR is a 16-bit transceiver in a different package (TSSOP) with 32 mA output drive and a minimum supply of 2.7 V.
