The EM74HC14; EM74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features  reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp  diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess  of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.
