Ultra-low-power dual buffer for space-constrained, battery-operated designs
The NXP 74AUP2G17GF,132 is a dual non-inverting buffer with Schmitt-trigger inputs from the 74AUP family — NXP's lowest-power CMOS logic series. The 6-XSON package measures just 1x1 mm, making it a fit for wearable, IoT sensor node, and portable medical designs where board area and battery life are the constraints.
Schmitt-trigger inputs — noise immunity for slow or noisy signals
The Schmitt-trigger input on each buffer provides hysteresis, cleaning up slow edges from RC-delayed signals, mechanical switches, or sensor outputs. In an industrial or mixed-signal environment, this prevents false triggering from coupled noise or ground bounce that a standard CMOS input would pass through.
The 0.8V to 3.6V supply range covers the full discharge curve of a lithium-ion battery (3.6V down to ~3.0V nominal, and further with a boost). It also interfaces directly with 1.2V, 1.8V, and 3.3V logic families without level translation. For a 1.8V MCU I/O, this buffer can clean and re-drive a signal to a peripheral at the same voltage.
The 125°C upper limit covers engine-compartment ambient and high-density PCB hotspots without derating.
Package and footprint — 6-XSON (1x1 mm)
The 6-XSON (1x1 mm) package is a leadless plastic package with a 0.35 mm pitch. It requires a fine-pitch PCB layout and a solder-paste stencil designed for small land patterns. The small size suits multi-layer boards in wearables and sensor modules where every square millimeter counts.
