This hysteresis rejects noise on slowly changing or noisy input signals, making the part suitable for debouncing switch contacts, squaring up oscillator waveforms, and interfacing with sensors that have slow edge rates. Quiescent current is a maximum of 2 µA across the supply range, keeping the standby power draw negligible in battery-powered or always-on subsystems. Each output can source or sink 5.2 mA, sufficient to drive CMOS logic inputs or low-current LEDs directly. Maximum propagation delay is 21 ns at 6 V with a 50 pF load, setting the practical toggle rate ceiling. For a 5 V system, the actual delay will be slightly longer; the 74HC family's speed is adequate for control logic, debounce circuits, and low-frequency clock conditioning up to several megahertz. The Tape & Reel (TR) and Cut Tape (CT) options allow both volume reel feeding and prototype quantities.","metaTitle":"SN74HC14DRG3 Texas Instruments 74HC Hex Schmitt Inverter","metaDescription":"Texas Instruments SN74HC14DRG3 hex Schmitt-trigger inverter, 2V-6V supply, -40°C to +85°C, 14-SOIC.
