description
The 'AC11014 contains six independent inverters.
They perform the Boolean function Y = A.
Because of the Schmitt action, the devices have
different input threshold levels for positive-going
(V
T+
) and for negative-going (V
T
) signals.
These circuits are temperature compensated.
They can be triggered from the slowest of input
ramps and still give clean, jitter-free output signals
and greater noise margin than conventional
inverters.
The 54AC11014 is characterized for operation
over the full military temperature range of 55
C
to 125
C. The 74AC11014 is characterized for
operation from 40
C to 85
C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
