To all Diode Junction Cathodes using a star

connection to pin. Must float when not used.

Manufacturing test pins. Left floating. PC board traces may be routed

through the pads for these pins, although the

components that drive these traces should share

the same supply as the LM83 so that the Absolute

Maximum Rating, Voltage at Any Pin, is not

violated.
