9.3.5 VIN and VBIAS Voltage Range

For optimal RON performance, make sure VIN ≤ VBIAS. The device is still functional if VIN > VBIAS, but it exhibits RON greater than what is listed in the Electrical Characteristics (VBIAS = 5 V) and Electrical Characteristics (VBIAS = 2.5 V) table. See Figure 30 for an example of a typical device. Notice the increasing RON as VIN exceeds VBIAS voltage. Be sure to never exceed the maximum voltage rating for VIN and VBIAS.
