description/ordering information

These Schmitt-trigger devices contain six independent inverters. They perform the Boolean function Y = A.

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.
