Note 1: Absolute maximum ratings are those values beyond which damage to the device may
occur. 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 TM circuits outside
databook specifications.
