Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions.
Note 2: Human Body Model, applicable std. JESD22-A114C
Note 3: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 4: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except V
ΔV
Note 5: Typical values represent most likely parametric norms for V
product characterization and are not guaranteed.
Note 6: Output short circuit current (I
Note 7: If input LVDS signal is below 20mV
Note 8: Parameter is guaranteed by characterization and is not tested at production.
Note 9: Recommended value, parameter is not tested.
Note 10: Recommended maximum capacitance load per bus segment is 400 pF.
