Single Schmitt-trigger buffer for noisy, low-voltage rails
It takes a noisy or slow-edged input and outputs a clean, fast push-pull signal, making it a go-to part for debouncing switches, conditioning sensor outputs, or interfacing with slow-rise-time oscillators. The supply range spans 0.8V to 3.6V, so it works directly from a single Li-ion cell or a 1.8V/2.5V/3.3V rail without a separate level translator.
The 0.8V minimum supply is unusually low for a standard logic buffer; most 74LVC or 74AHCT parts stop at 1.65V or 2V. This part lets a 0.9V or 1.2V core rail drive a buffer directly, saving a regulator or level-shifter IC.
SOT-553 footprint and board integration
Housed in a 5-pin SOT-553 package, this buffer takes up roughly 1.6 mm × 1.6 mm of board area. That makes it a strong fit for space-constrained designs like wearables, sensor modules, or compact IoT nodes. The small pads mean hand-soldering is tricky — a reflow profile with a fine-pitch stencil is the reliable assembly route.
ROHS3 compliance is confirmed.
