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.
The q denotes specifications which apply over the full operating temperature range.
VCC = 3.3V, C1 = C2 = C3 = C4 = 0.1F, unless noted.
The q denotes specifications which apply over the full operating
