Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. Obviously the databook specifications should be
met, without exception, to ensure that the system design is reliable over its
power supply, temperature, and output/input loading variables. National does
not recommend operation of FACT® circuits outside databook specifications.
