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.
