All VCC Pins

a. The MPC9447 is capable of driving 50Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated

transmission line to a termination voltage of VTT. Alternatively, the device drives one 50Ω series terminated transmission lines per output

(VCC=2.5V).

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 50Ω 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 |.
