Absolute Maximum Ratings
NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond
those listed in the DC Characteristics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect product reliability.

NOTE: Refer to the Power Considerations section. In LVDS output mode, the I_DD, I_DDA and I_DDO specifications apply. I_DDO is the current
through all V_DDOA and V_DDOB pins. In LVPECL mode, the IGND specification applies. IGND is the current through all GND pins.
