Note 2: “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:

Note 7: Supply current specification is valid for loaded transmitters when DE = 0V or enabled (DE = H) with no load.
