The q denotes specifications which apply over the operating temperature
range (0
°C ≤ TA ≤ 70°Cfor commercial grade, – 40°C ≤ TA ≤ 85°C for
industrial grade).
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: Supply current and leakage current measurements in SHUTDOWN
are performed with VON/OFF = 0V.
