3 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 resistance1
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.

Junction-to-case thermal resistance2
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.
