    Hi Shimizu-san ,

    Usually , only fmax has only min specified .Max depends on the system it is driving the output into and the load conditions .You can use the fclock frequency for all your reference . fclock spec is for the user telling how fast device can reliably switch and fmax is for TI to reject the device which doesn't perform below the minimum speed . Of course, again , the speed of the device depends on external conditions of cap load, temperature etc which will be specified in the datasheet .
