* Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in

the Electrical Characteristics tables.

** Derating: – 12 mW/

°C from 25° to 60°C.

*** Derating: – 3.5 mW/

°C from 25° to 60°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, Vin and

Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD except for the I/O, which can exceed VDD, and the Test input, which can go

below VSS.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs and/or an unused I/O must

be left open.
