SN74LVC2G17DCKR

SN74LVC2G17DCKR packs two independent Schmitt-trigger buffers into a six-pin SC70 (DCK) package for board-level signal conditioning. The selection point is the Schmitt-trigger input itself: slow, noisy or bouncing edges from push-buttons, sensor comparators, RC reset networks and long cable runs are squared up into clean logic transitions, with the hysteresis band rejecting the false toggles a plain buffer would pass through. The device runs from 1.65 V to 5.5 V, so one stocking code covers 1.8 V, 2.5 V, 3.3 V and 5 V domains, and its inputs tolerate voltages above the supply rail, which helps when the driving side is powered from a higher domain. Partial-power-down protection keeps the outputs from back-driving an unpowered rail, a real concern in hot-swap and battery-backed designs. Selection advice: place the 2G17 directly behind any input that arrives with a slow ramp or mechanical contact, rather than relying on the Schmitt specification of a downstream MCU pin, which is often loosely characterised. If you only need plain buffering without hysteresis, the LVC2G34 sibling in the same footprint is the simpler part. Parameters verified against Texas Instruments documentation.
