Schmitt-trigger buffer for noisy signal lines
The SN74LVC2G17DSF2 is a dual non-inverting buffer with Schmitt-trigger inputs, part of the 74LVC logic family from Texas Instruments. It cleans up slow or noisy edges on digital lines — the hysteresis at the input rejects glitches that a standard buffer would pass through to the downstream logic. The output can source or sink 32 mA per channel, enough to drive a standard CMOS load or a low-power LED indicator directly.
Surface-mount only; no through-hole variant. The 125°C ceiling gives margin above the 85°C commercial limit for outdoor or engine-bay deployment.
