(1) Typical values represent most likely parametric norms at VDD = 3.3V, TA = +25°C, and at the Recommended Operating Conditions at
the time of product characterization and are not verified.
(2) Current into a the device is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground
except VOD, ÎVOD, VTH, VTL which are differential voltages.
(3) DIGITAL, PLL, AND ANALOG VDDS
