Dual buffer with Schmitt-trigger inputs in a 1x1mm SON
The Texas Instruments SN74AUP2G17DSFR is a dual non-inverting buffer from the 74AUP low-power logic family, featuring Schmitt-trigger inputs for noise-tolerant signal conditioning. It operates across a 0.8V to 3.6V supply range, making it suited for battery-powered and low-voltage portable designs. Each of the two elements drives up to 4mA source and sink, enough to fan out to multiple CMOS logic inputs. The industrial temperature grade (-40°C to 85°C) covers most indoor and outdoor telecom, industrial control, and consumer equipment.
Supply voltage range and what it enables
The 0.8V to 3.6V supply span directly matches the core voltages of modern low-power MCUs, FPGAs, and SoCs. At the low end, it interfaces cleanly with 1.2V or 1.8V logic without an external level translator. At 3.6V it handles legacy 3.3V rails. The Schmitt-trigger input provides hysteresis that cleans up slow edges from RC debounce circuits, sensor comparators, or long PCB traces — a common need in panel interfaces and pushbutton inputs.
Package and layout reality
Housed in a 6-XFDFN (6-SON) package measuring 1x1mm, this part is sized for dense PCB layouts where every square millimetre counts — think wearable, IoT sensor nodes, or multi-channel interface modules. The small footprint means the board assembler needs to handle DFN-style packages; the 0.5mm pitch is standard for that class. No exposed thermal pad to worry about, but the tiny body demands precise stencil aperture for solder paste.
Lifecycle and sourcing posture
The SN74AUP2G17DSFR carries an Active product status and is ROHS3 compliant. No last-time-buy or obsolescence risk on the horizon.
