2. 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.
3. CAUTION: All “5 V Tolerant” input voltages cannot 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 must not be higher than 5.75 V. “5
V Tolerant” inputs are inputs that tolerate 5 V.

Notes: 1. Junction-to-ambient thermal resistance is based on measurements on a horizontal single-sided printed circuit board per
JEDEC Specification 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.
3. These are simulated values. See note 1 for test board conditions.
4. These are simulated values. The test board has two 2-ounce signal layers and two 1-ounce solid ground planes internal to
the test board.
