Note:
1. Functional and tested operating conditions are given in Table ”Recommended Operating Conditions1,2,3,” below. Absolute maximum ratings are
stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause per-
manent damage to the device.
