description
These Schmitt-trigger devices contain six
independent inverters. They perform the Boolean
function Y = A. Because of the Schmitt action, they
have different input threshold levels for
positive-going (V
T+
) and for negative-going (V
T–
)
signals.
These circuits are temperature compensated and
can be triggered from the slowest of input ramps
and still give clean, jitter-free output signals. They
also have a greater noise margin than
conventional inverters.
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.
