* Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.

NOTES:
1. V
OUT
outputs open circuited.
2. V
OUT
is 0V through approximately 100k
to ground when CE = V
IH
.
3. Recovery time is the period required for V
OUT
to rise from 0V (shutdown state) to the voltage corresponding to the measured
temperature driving a 100pF capacitive load.
4. Accuracy = Difference between calculated output voltage (10mV/
°
C x Device case temperature at specified temperature and power
supply) and measured output voltage expressed in
°
C.
5. Nonlinearity = deviation of output voltage versus temperature from the best-fit straight line over the device rated temperature range.
