Switching Characteristics
Over Supply Voltage and Operating Temperature ranges, unless otherwise specified. (Notes 6, 8, 9, 10)
Note 4: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 5: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise
specified (such as V
Note 6: All typicals are given for: V

Note 8: These parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over PVT (process, voltage,
temperature) ranges.
