description
The SN65LVDS047 is a quad 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
EIA/TIA-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.

The intended application of this device and
signaling technique is for point-to-point and multidrop baseband 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, the noise coupling to the environment, and other system characteristics.
The SN65LVDS047 is characterized for operation from −40°C to 85°C.
