0.8 V to 2.7 V supply — the sub-1V buffer this BOM needs
The Texas Instruments SN74AUC2G126DCUR is a dual non-inverting buffer with 3-state outputs from the 74AUC series, designed for the 0.8 V to 2.7 V supply range. Each of the two elements handles one bit, sourcing or sinking 9 mA per channel. The 8-VSSOP package (2.30 mm width) keeps the footprint small for dense PCBs. This part is meant for low-voltage digital buses — think sub-1 V core logic, battery-powered handhelds, or voltage-translation interfaces where the I/O rails run below 2.7 V.
9 mA output drive — what it means for your bus
At 9 mA source and 9 mA sink, this buffer is not a heavy line driver. It is sized for short PCB traces, control signals, or clock enables — not for driving a 50 Ω backplane or a long cable. If your load capacitance or fan-out exceeds a few standard CMOS inputs, check the DC and AC margins against the datasheet's VOH/VOL curves at your actual supply voltage. At 0.8 V the drive capability drops further, so keep the trace length under a few inches.
Industrial temperature grade — -40°C to 85°C
Rated for -40°C to 85°C ambient, this buffer covers the majority of industrial, telecom, and commercial equipment. It is not AEC-Q100 qualified, so it is not a fit for under-hood automotive or extended-temperature outdoor enclosures without qualification testing. For a 125°C-rated alternative in a similar footprint, look at the 74LVC or 74AHC families.
Active production — no LTB risk
The SN74AUC2G126DCUR carries an Active product status and is ROHS3 compliant. There is no end-of-life notice or last-time-buy window to manage. Standard lead times apply through distribution channels.
