The SN74AUP2G32DQER: It packages two independent OR gates in a single 8-X2SON (1.4x1 mm) package, each with two inputs and a single output. The part is designed for battery-powered and portable equipment where every microamp matters — quiescent current maxes out at 500 nA across the full 0.8V to 3.6V supply range. Propagation delay sits at 6.2 ns driving a 30 pF load at 3.3V, fast enough for general-purpose glue logic in sensor interfaces, level translation, and power sequencing circuits.
Supply range and quiescent current — the battery-design decision
The 0.8V to 3.6V supply range is the headline feature of the 74AUP family. It lets this OR gate run directly from a single Li-ion cell (3.0V to 4.2V) or a pair of alkaline cells (1.8V to 3.0V) without a regulator. At the low end, 0.8V operation means it can interface with sub-1V core logic in modern MCUs and SoCs. The 500 nA maximum quiescent current is the practical spec that makes this part the right choice over older families like 74LVC or 74AHC — those draw tens to hundreds of microamps in standby.
Package and footprint — 8-X2SON (1.4x1 mm)
The SN74AUP2G32DQER comes in an 8-XFDFN package, with the supplier device package listed as 8-X2SON measuring 1.4x1 mm. The exposed pad is not present on this package variant; all eight pins are on the perimeter. For rework, the small body mass means it reaches reflow temperature quickly; use a hot-air profile tuned for small DFN packages to avoid tombstoning. The package is rated MSL 1 by default for the 74AUP series, but verify the moisture sensitivity on the reel label before opening the bag.
