NOTE: Four pins (VRL0, VRH0, VRL1, and VRH1) show ESD susceptibility
below the Motorola standards. Care should be exercised in handling
these pins.
Table 21-1. Maximum Ratings

1. Permanent damage can occur if maximum ratings are exceeded. Exposures to voltages or currents in excess of recom-
mended values affects device reliability. Device modules may not operate normally while being exposed to electrical ex-
tremes.

3. One pin at a time, observing maximum power dissipation limits. Internal circuitry protects the inputs against damage caused
by high static voltages or electric fields; however, normal precautions are necessary to avoid application of any voltage high-
er than maximum-rated voltages to this high-impedance circuit. Extended operation at the maximum ratings can adversely
affect device reliability. Tying unused inputs to an appropriate logic voltage level (either GND or V
DD
) enhances reliability
of operation.
