* Absolute maximum continuous ratings are those values beyond which damage to the device
may occur. Exposure to these conditions or conditions beyond those indicated may adversely
affect device reliability. Functional operation under absolute−maximum−rated conditions is not
implied.

TSSOP Package: − 6.1 mW/_C from 65_ to 125_C
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must be
taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance cir-
cuit. For proper operation, V_in and
V_out should be constrained to the
range GND v (V_in or V_out) v V_CC.
Unused inputs must always be tied
to an appropriate logic voltage level
(e.g., either GND or V_CC). Unused
outputs must be left open.
