description/ordering information
In these devices, each circuit functions as a
quadruple NOR gate. They perform the Boolean
function Y = A • B or Y = A + B in positive logic.
However, because of the Schmitt action, the
inputs have different input threshold levels for
positive- and negative-going signals.
These circuits are temperature compensated and
can be triggered from the slowest of input ramps
and still give clean jitter-free output signals.
