* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or
conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute--maximum--rated conditions is
not implied.

CCQd
a. V
CMR
(DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the V
CMR
range
and the input swing lies within the V
PP
(DC) specification.
b. Input pull-up / pull-down resistors influence input current.
c. The MPC9448 is capable of driving 50
transmission lines on the incident edge. Each output drives one 50
parallel terminated
transmission line to a termination voltage of V
TT
. Alternatively, the device drives up to two 50
series terminated transmission lines (for
VCC=3.3V) or one 50
series terminated transmission line (for VCC=2.5V).
d. I
CCQ
is the DC current consumption of the device with all outputs open and the input in its default state or open.
