... It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. Pin configuration and function are the same as those of the 74LCX04 but the 74LCX14 has hysteresis between the positive and negative input threshold typically of 0.8V. This together with its schmitt trigger function allows used on line receivers with slow rise/fall input signals ...
