ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃ Maximum ratings are those values beyond which device damage can occur. Maximum ratings
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 highâimpedance cir-
cuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
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.
â Derating â Plastic DIP: â 10 mW/_C from 65_ to 125_C
SOIC Package: â 7 mW/_C from 65_ to 125_C
TSSOP Package: â 6.1 .W/_C from 65_ to 125_C
