1. Functional and tested operating conditions are given in Table 3-2, “Recommended Operating Conditions” on page 10. Absolute
maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those
listed above may affect device reliability or cause permanent damage to the device.
2. Caution: Transient V overshoots of up to OV + 0.8V, with a maximum of 4.0V for 3.3V operation, and undershoots down to
