The Schmitt-trigger inputs accept slow edges (e.g., from RC debounce circuits or long PCB traces) without oscillation, with a typical hysteresis of several hundred millivolts. Quiescent current maxes at 2 µA, so it adds negligible standby draw in battery-backed systems. The SN74HCS02BQAR is an active, ROHS3-compliant part from TI's 74HCS series.","metaTitle":"SN74HCS02BQAR Quad 2-Input NOR Gate, Schmitt Trigger, 2V-6V","metaDescription":"TI SN74HCS02BQAR quad 2-input NOR gate with Schmitt-trigger inputs, 2V-6V supply, -40°C to 125°C.
