Maximum ratings are those values beyond which device damage can occur. Maximum ratings
applied to the device are individual stress limit values (not normal operating conditions) and are
not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
†Derating — SOIC Packages: – 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 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.
