SN65LVDS047 is a four-difference line driver that features operating from -40°C to 85°C, achieving the electrical characteristics of low-voltage differential signals (LVDS). This signaling technique reduces the output voltage level at a 5 v differential standard level (such as EIA/TIA-422B) to reduce power, increase switching speed, and allow for running with a 3.3v power supply track. Any of the four current mode drivers will provide a minimum differential output voltage of 247 mV to a 100-Ω load when enabled.
Pin arrangement
The intended application of the device and signaling technology is point-to-point and multi-drop baseband data transmission over controlled impedance media of approximately 100 Ω. The transmission medium can be printed circuit board wiring, backboard, or cable. The final rate and distance of data transmission depends on the attenuation characteristics of the medium, noise coupling to the environment, and other system characteristics.
