The SN74LVC3G14DCUR is a triple Schmitt-trigger inverter from Texas Instruments' 74LVC series, designed for general-purpose logic inversion with built-in hysteresis on all three inputs. Each of the three channels can sink or source 32 mA, making it capable of driving moderate loads like LED indicators or downstream gate inputs directly. The quiescent current maxes at 10 µA, so it adds negligible draw to a power budget in battery-powered or always-on circuits.
Package and board integration for field replacement
Housed in an 8-VFSOP (also marked as 8-VSSOP) package with a 2.30 mm body width, this is a small-outline surface-mount part that fits tight PCB layouts without requiring a fine-pitch reflow profile beyond standard 0.65 mm pitch.
Schmitt-trigger hysteresis and propagation delay for noise-prone lines
The Schmitt-trigger inputs provide defined switching thresholds: low-level input from 0.3 V to 1.4 V, high-level from 1.4 V to 3.7 V, which cleans up slow or noisy edges on sensor outputs or long PCB traces.
