Single Schmitt-trigger inverter in a 1-mm² SON
It operates from 0.8 V to 3.6 V and draws a maximum quiescent current of 500 nA, making it a fit for battery-powered and always-on circuits where every microamp counts. The Schmitt-trigger hysteresis cleans up slow or noisy input edges — think sensor outputs, pushbutton debounce, or RC oscillator buffers — that would cause a standard inverter to oscillate or draw shoot-through current. Propagation delay is 6.2 ns at 3.3 V with a 30 pF load, fast enough for most low-frequency digital buses and GPIO level translation.
Package and footprint — 6-SON (1x1 mm)
The DSFR suffix denotes a 6-pin XFDFN (also called SON) package measuring 1 mm × 1 mm. The supplier device package is 6-SON (1x1).
