MC74AC14 Datasheet, PDF (1/8 Pages) ON Semiconductor – Hex Inverter Schmitt Trigger

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,
jitter–free output signals. In addition, they have a greater noise
margin then conventional inverters.
The MC74AC14/74ACT14 has hysteresis between the
positive–going and negative–going input thresholds (typically 1.0 V)
which is determined internally by transistor ratios and is essentially
insensitive to temperature and supply voltage variations.
• Schmitt Trigger Inputs
• Outputs Source/Sink 24 mA
• ′ACT14 Has TTL Compatible Inputs
