ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃ *Maximum Ratings are those values beyond which damage to the device may occur.
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
v v Vout should be constrained to the
range GND (Vin or Vout) 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.
Functional operation should be restricted to the Recommended Operating Conditions.
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 mW/_C from 65_ to 125_C
For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor HighâSpeed CMOS Data Book (DL129/D).
