Each gate accepts a single input and inverts the logic state, with the Schmitt trigger providing hysteresis that cleans up noisy or slow-rising signals. ## Temperature range and timing The quiescent current maxes out at 2 µA, so battery-powered remote sensors and always-on monitoring circuits don't drain the cell during idle periods. Propagation delay is 16 ns maximum at 6 V with a 50 pF load. That gives a clean switching window for clock conditioning, debouncing switch inputs, or squaring up sensor edges before feeding them into a microcontroller GPIO. ## Package and board integration The 0.5 mm pitch pads need a controlled impedance trace width for signal integrity at the gate's switching speed, though the 16 ns delay means edge rates are moderate. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel format suits automated pick-and-place for volume production, while cut tape works for prototype runs and small-batch builds. The part is ROHS3 compliant, meeting the current EU restriction directive for lead-free soldering processes.","metaTitle":"SN74HCS14BQAR Texas Instruments Hex Inverter","metaDescription":"Texas Instruments SN74HCS14BQAR hex inverter with Schmitt trigger inputs. 2V-6V supply, -55°C to 125°C, 14-QFN exposed pad.
