NOTE:
1.The frequency dependent specifications are greatly influenced by the PCB layout in the application. These specifications have all been measured
using a Motorola application layout and circuit similarly as shown in Figures 19 and 21. The reference number for ordering this evaluation board
is MC44350EVK.
