Schmitt-trigger inverter for noisy signal conditioning
The SN74ALVC14DR is a hex inverter from TI's 74ALVC family, each channel with a Schmitt-trigger input. It inverts a single input per channel across six independent circuits, cleaning up slow or noisy edges into a clean digital output. The Schmitt thresholds are specified at 0.35 V to 0.8 V for low-level and 1.7 V to 2.0 V for high-level, giving hysteresis that rejects noise on long traces or from inductive coupling. Output drive is 24 mA source and sink at 3.3 V, enough to switch a standard CMOS load or drive a short PCB trace without a buffer. Propagation delay is 3.4 ns max at 3.3 V into 50 pF, so the part handles clock rates well above 100 MHz in a clean layout.
Package, temperature, and board-fit note
The supplier device package is 14-SOIC; the reel is offered in Tape & Reel (TR) or Cut Tape (CT) options. Quiescent current is 10 µA max, so the part adds negligible draw in battery-powered or always-on systems.
It is ROHS3 compliant, with no exemptions that would limit its use in EU or North American production.
