Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.
†Derating: SOIC Package: –7 mW/_C from 65_ to 125_C
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
circuit. 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.
