The MM74HC14 is a hex Schmitt-trigger inverter from Fairchild Semiconductor (now ON Semiconductor). This device contains six independent inverters, each of which performs the logical INVERT function. It's characterized by its Schmitt-trigger inputs, which provide different input threshold voltages for positive-going and negative-going signals. This hysteresis characteristic makes the MM74HC14 ideal for use in applications where input signals may be noisy or slowly changing.
