The q denotes specifications which apply over the operating temperature
range (0
°C ≤ TA ≤ 70°C for commercial grade and –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: Testing done at VCC = 5V and VON/OFF = 3V. C1 = C2 = 0.2µF,
C+ = C = 0.1
µF.
Note 3: Supply current is measured with driver and receiver outputs
unloaded and the driver inputs tied high.
Note 4: Supply current and leakage current measurements in shutdown
are performed with VON/OFF = 0.1V. Supply current measurements using
DRIVER DISABLE are performed with VDRIVER DISABLE = 3V.
Note 5: For driver delay measurements, RL = 3k and CL = 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (tHL = 1.4V to 0V and tLH = 1.4V to 0V).
Note 6: For receiver delay measurements, CL = 51pF. Trigger points are set
between the receiver’s input logic threshold and the output transition to
standard TTL/CMOS logic threshold (tHL = 1.3V to 2.4V and tLH = 1.7V to
0.8V).
Note 7: Absolute maximum externally applied voltage. Internal charge
pump may force a larger value on this pin.
