Table 1. Pin Descriptions
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Temperature shutdown pin. Can
be used as a logic level input or an
output. See Tables 16 and 17,
Truth Tables, and the Switching
Behavior section of this data sheet
for input pin description. As an
output flag, will read 5 V when the
device is in its operational mode
and 0 V in the thermal shutdown
mode. To disable the thermal shut-
down mechanism, tie this pin to
5 V (
not
recommended).
