DESCRIPTION
The SN65LVDS31 is a differential line driver that implements 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. This driver will deliver a minimum differential output voltage magnitude of 247 mV into a 100-Ω
load when enabled.
The intended application of this device and signaling technique is both point-to-point and multidrop (one driver
and multiple receivers) data transmission over controlled impedance media of approximately 100 Ω. 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 SN65LVDS31 is characterized for operation from –55°C to 125°C.
