The SN75LVDS31 and SN75LVDS9638 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 for point-to-point baseband 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.
The SN75LVDS31 and SN75LVDS9638 are characterized for operation from 0°C to 70°C.
