description  
These Schmitt-trigger devices contain six  
independent inverters. They perform the Boolean  
functionY=A. BecauseoftheSchmittaction, they  
have different input threshold levels for

These circuits are temperature compensated and  
can be triggered from the slowest of input ramps  
and still give clean, jitter-free output signals. They

SN54ACT14 is characterized for operation over  
the full military temperature range of –55°C to  
125°C. The SN74ACT14 is characterized for  
operation from –40°C to 85°C.
