Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the maximum rating may affect device reliability or cause permanent damage to the device.

CAUTION:
All “5 V Tolerant” input voltages must not be more than 3.95 V greater than the supply voltage; this restriction
applies to “power on”, as well as during normal operation. In any case, the input voltages cannot be more than 5.75 V. “5 V
Tolerant” inputs are inputs that tolerate 5 V.

Junction-to-ambient thermal resistance
1
1
Junction-to-ambient thermal resistance is based on measurements on a horizontal single-sided printed circuit board per SEMI
G38-87 in natural convection.(SEMI is Semiconductor Equipment and Materials International, 805 East Middlefield Rd.,
Mountain View, CA 94043, (415) 964-5111.)
Measurements were done with parts mounted on thermal test boards conforming to specification EIA/JESD51-3.
2
Junction-to-case thermal resistance is based on measurements using a cold plate per SEMI G30-88, with the exception that
the cold plate temperature is used for the case temperature.
