Single-gate Schmitt buffer for noise-prone lines
The SN74LVC1G17DCK3 is a single-channel non-inverting buffer with Schmitt-trigger input, belonging to the 74LVC low-voltage CMOS family. It cleans up slow or noisy edges on a digital line and presents a clean push-pull output to the next stage.
Output drive and signal integrity margin
Each output sources or sinks 32 mA at 3.3 V — enough to drive a logic input fan-out of ten or more, or to switch a small LED indicator directly without a transistor buffer. The Schmitt-trigger hysteresis (typical 0.5 V at 3.3 V) rejects noise on long PCB traces or ribbon cables; a signal with 300 mV of ripple still produces a clean output transition.
SC-70-5 footprint and board integration
Supplied in the 5-pin SC-70-5 (SOT-353) package, the part occupies roughly 2.0 mm × 2.1 mm — fits into a tight corner near the connector or sensor where signal conditioning is needed. The tape-and-reel or cut-tape option lets prototype builds and low-volume production share the same BOM line without minimum-reel constraints.
Active lifecycle and compliance
It is ROHS3 compliant and free of the six restricted substances under EU RoHS. The base product number 74LVC1G17 covers the whole family; the DCK3 suffix identifies the SC-70-5 tape-and-reel variant. No pin-compatible second-source is on the ledger, but the part is widely sourced through authorized distribution.
