Maximum ratings are those values beyond which device damage can occur. Maximum ratings

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.

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 cir-

range GND

Unused inputs must always be

tied to an appropriate logic voltage

Unused outputs must be left open.
