74HCT14 Hex Schmitt−Trigger Inverter with LSTTL Compatible Inputs High−Performance Silicon−Gate CMOS The 74HCT14 may be used as a level converter for interfacing TTL or NMOS outputs to high−speed CMOS inputs. The HCT14 is useful to “square up” slow input rise and fall times. Due to the hysteresis voltage of the Schmitt trigger, the HCT14 finds applications in noisy environments.
