3 Description

The SN55LVDS31, SN65LVDS31, SN65LVDS3487,

and SN65LVDS9638 devices are differential line

drivers that implement the electrical characteristics

of low-voltage differential signaling (LVDS). This

signaling technique lowers the output voltage levels

of 5-V differential standard levels (such as TIA/

EIA-422B) to reduce the power, increase the

switching speeds, and allow operation with a 3.3-V

supply rail. Any of the four current-mode drivers

will deliver a minimum differential output voltage

magnitude of 247 mV into a 100-Ω load when

enabled.
