DESCRIPTION  
The SN55LVDS31, SN65LVDS31, SN65LVDS3487,  
and SN65LVDS9638 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-load when enabled.

The intended application of these devices and  
signaling technique is both point-to-point and  
multidrop (one driver and multiple receivers) data  
transmission over controlled impedance media of  
approximately 100 . The transmission media may  
be printed-circuit board traces, backplanes, or  
cables. The ultimate rate and distance of data  
transfer is dependent upon the attenuation  
characteristics of the media and the noise coupling  
to the environment.
