• Manufacturer: Motorola

MPC9448
a. AC characteristics apply for parallel output termination of 50Ω to V
b. V
c. 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
d. Output pulse skew is the absolute difference of the propagation delay times: | t
a. V
b. Input pull-up / pull-down resistors influence input current.
c. The MPC9448 is capable of driving 50Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated

is the DC current consumption of the device with all outputs open and the input in its default state or open.
(AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the V
(DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the V
