Single Schmitt-trigger inverter in SOT-753
The Nexperia XC7SH14GV,125 is a single-gate Schmitt-trigger inverter from the 7SH series, housed in a 5-pin SOT-753 (SC-74A) package. It accepts one input and delivers a clean inverted output with hysteresis, making it the go-to choice for debouncing switch contacts, squaring up slow edges from RC oscillators or sensors, and providing noise-immune logic-level translation in mixed-voltage boards. The supply range spans 2V to 5.5V, covering 3.3V and 5V logic families without a separate regulator. Quiescent current maxes out at 1 µA, which keeps the standing power negligible in battery-operated edge nodes.
With a maximum propagation delay of 10.6 ns at 5V into a 50 pF load, this inverter clears the timing budget for most 20–50 MHz clock and data paths. At lower supply voltages the delay increases, but the Schmitt-trigger input thresholds (low: 0.9V to 1.65V; high: 2.2V to 3.85V at 5V) guarantee clean switching even when the input ramp is slow or noisy.
