Product details

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).

Frequently asked questions

Is SN74AUP1G14DSFR a direct replacement for SN74AUP1G14DCKR?

The SN74AUP1G14DCKR is the same die in a different package (SC-70-5 vs 6-SON). Electrically they are identical, but the footprint and pinout differ — the DCKR uses a 5-pin SOT-23/SC-70 layout, while the DSFR uses a 6-pin 1×1 mm SON. They are not drop-in replacements without a board layout change.
