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

a. The MPC9447 is capable of driving 50
transmission lines on the incident edge. Each output drives one 50 parallel terminated transmis-
sion line to a termination voltage of VTT. Alternatively, the device drives up to two 50 series terminated transmission lines (for VCC=3.3V).
b. Inputs have pull-down or pull-up resistors affecting the input current.
c. ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.

a. AC characteristics apply for parallel output termination of 50
to VTT.
b. Violation of the 1.0 ns maximum input rise and fall time limit will affect the device propagation delay, device-to-device skew, reference input
pulse width, output duty cycle and maximum frequency specifications.
c. Setup and hold times are referenced to the falling edge of the selected clock signal input.
d. Output pulse skew is the absolute difference of the propagation delay times: | tPLH - tPHL |.
