1. Absolute maximum continuous ratings are those maximum 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 at absolute-maximum-rated conditions is not implied.

1. The MPC9447 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 V
CC
= 3.3 V).
2. Inputs have pull-down or pull-up resistors affecting the input current.
3. I
CCQ
is the DC current consumption of the device with all outputs open and the input in its default state or open.
