Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing done at V
Note 3: Supply current is measured as the average over several charge
pump burst cycles. C

Note 6: For driver delay measurements, R
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (t
Note 7: For receiver delay measurements, C
set between the receiver’s input logic threshold and the output transition
to standard TTL/CMOS logic threshold (t
to 0.8V).
Note 8: Data rate operation guaranteed by slew rate, short-circuit current
and propagation delay tests.
