The q denotes specifications which apply over the operating temperature
range 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 outputs
unloaded.
Note 3: Measurements made in the Driver Disable mode are performed
with VDRIVER DISABLE = GND and VON/OFF = VCC.
Note 4: Measurements made in the Shutdown mode are performed with
VON/OFF = 0V.
