9.3.2.6 NC Pins

NC (not connected) pins are pins where the die is not physically connected to the lead frame or package. For

optimum thermal performance, a good rule of thumb is to ground the NC pins at the board level.

9.4 Device Functional Modes

When the SN65LVDS1 is operated with its supply voltage less than 1.5 V, the driver output pins are high-

impedance. When the SN65LVDS2 or the SN65LVDT2 is operated with its supply voltage less than 1.5 V, both

the receiver input and the receiver output pins are high-impedance.

9.4.2 Operation With 1.5 V

Operation with supply voltages in the range of 1.5 V

performance is guaranteed in this range.

9.4.3 Operation With 2.4 V

Operation with the supply voltages greater than or equal to 2.4 and less than or equal to 3.6 V is normal

operation. Some device specifications apply across the full supply range of 2.4 V

specifications are dependent upon the supply voltage. These dependencies are clearly described in the

parametric tables above, as well as shown in the Typical Characteristics section.

9.4.4 SN65LVDS1 Truth Table

As can be seen from the truth table, when the driver input is left open, the differential output will be driven low.
