Additional Details

The MM74LCX14D is a hex inverting Schmitt trigger, meaning it contains six independent inverting gates with Schmitt trigger inputs. The input hysteresis provides a noise margin, making the device less susceptible to false triggering. The output drive capability (IOH/IOL) and propagation delay times depend on the supply voltage and load capacitance.
