MC74AC14, MC74ACT14  
Hex Inverter Schmitt  
Trigger  
The MC74AC14/74ACT14 contains six logic inverters which  
accept standard CMOS Input signals (TTL levels for MC74ACT14)  
and provide standard CMOS output levels. They are capable of  
transforming slowly changing input signals into sharply defined,  
jitterfree output signals. In addition, they have a greater noise margin  
then conventional inverters.

The MC74AC14/74ACT14 has hysteresis between the  
positivegoing and negativegoing input thresholds (typically 1.0 V)  
which is determined internally by transistor ratios and is essentially  
insensitive to temperature and supply voltage variations.
