Notes:
1) Vt+(Vp) is the positive going threshold voltage.
2) Vt-(Vn) is the negative going threshold voltage.
3) Vh(ΔVt) is the hysteresis voltage
In UDMA modes greater than 4, the following characteristics apply. Voltage output high and
low values shall be met at the source connector to include the effect of series termination.
