The q denotes specifications which apply over the operating temperature
(0
°C ≤ TA ≤ 70°C).
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 output
unloaded and driver inputs tied high.
Note 3: Supply current measurement in SHUTDOWN mode is performed
with VON/OFF = 0V.
