Note 1: Absolute Maximum Ratings are those values beyond which the life

of the device may be impaired.

Note 2: Supply current is measured with driver and receiver outputs

unloaded.

Note 3: Measurements made in the Driver Disable mode are performed

Note 4: Measurements made in the Shutdown mode are performed with
