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).
