* 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.

a. VCMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the VCMR range

and the input swing lies within the VPP (DC) specification.

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

transmission line to a termination voltage of VTT. Alternatively, the device drives up to two 50Ω series terminated transmission lines (for

VCC=3.3V) or one 50Ω series terminated transmission line (for VCC=2.5V).

d. ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.
