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.

1. Temperature Derating: “D/DW” Package: –7.0 mW/

_C From 65_C To 125_C

2. POHmax = IOH (VOH − VDD) and POLmax = IOL (VOL − VSS)

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.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
