3、 device. The VBB output could be used to supply the input threshold level to one side of a differential input pair in a single ended reception mode. VIHmin and VILmax represent the guaranteed input HIGH and LOW threshold levels, respectively, for the device. VOH(C) anciV0uc) represent the output HIG

4、H and LOW threshold levels, respectively, with the inputs set to their respective threshold levels. See Appendix A for a graphic representation of these parameters.
