The Schmitt-trigger input has different threshold voltages for rising and falling edges: the positive-going threshold (VT+) is typically 2.2V at 3.3V supply, and the negative-going threshold (VT-) is typically 1.0V at 3.3V supply, giving a hysteresis of approximately 1.2V. This hysteresis provides noise immunity and converts slowly-changing or noisy input signals into clean, fast output transitions. Without hysteresis, a standard inverter would oscillate when the input voltage is near the switching threshold (approximately 1.65V at 3.3V supply). The Schmitt-trigger eliminates this problem, making it ideal for: (1) Switch debouncing - mechanical switches produce bouncing signals that are cleaned by the hysteresis; (2) Signal conditioning - converting analog sensor outputs to digital logic levels; (3) RC oscillator - the hysteresis enables relaxation oscillator circuits where a capacitor charges\/discharges between VT+ and VT-; (4) Level translation - the wide input threshold range accommodates signals from different voltage domains. The AHC family provides balanced propagation delays of 5ns at 5V and 8ns at 3.3V. The output can source\/sink 8mA at 5V and 4mA at 3.3V. The quiescent supply current is 1uA maximum.","pin_description":"
