11.1 MAXIMUM RATINGS

Rating	Symbol	Value	Unit
Supply Voltage 1, 2	V	–0.3 to +6.5	V
	CC
Input Voltage1, 2	Vin	–0.3 to +6.5	V
Operating Temperature Range	TA	0 to 70	°C
		or
		–40 to +85

NOTES:

1.Permanent damage can occur if maximum ratings are exceeded. Exposure to voltages or currents in excess of recommended values affects device reliability. Device modules may not operate normally while being exposed to electrical extremes.

2.Although sections of the device contain circuitry to protect against damage from high static voltages or electrical fields, take normal precautions to avoid exposure to voltages higher than maximum-rated voltages.

This device contains protective circuitry against damage due to high static voltages or electrical fields; however, it is advised that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (e.g., either GND or V CC ).
