Single Schmitt-trigger buffer for noise-prone signal lines
The SN74LVC1G17DBVR is a single non-inverting buffer with Schmitt-trigger input, part of TI's 74LVC logic family. The Schmitt-trigger input provides hysteresis that cleans up slow or noisy edges — a common requirement on long PCB traces, mechanical switch debounce, or sensor outputs where the rise time exceeds the logic threshold window.
Supply voltage and output drive across temperature
Rated for 32 mA source and sink at the output (push-pull), the buffer can drive moderate loads such as LED indicators, optocoupler inputs, or the clock input of a downstream flip-flop without an external buffer. The operating temperature range spans -40°C to +125°C (TA), covering industrial and automotive ambient conditions.
SOT-23-5 footprint and board integration
Housed in a 5-pin SOT-23-5 (SC-74A) package, the part occupies minimal board area — roughly 3.0 mm × 1.5 mm. The small footprint suits dense mixed-signal designs where one extra buffer cleans up a single noisy line without dedicating a larger SOIC or TSSOP.
