† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Description

The SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 aredifferential 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 SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 delivers a minimum differential output voltage magnitude of 247 mV into a 100- load when enabled.

The intended application of SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 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 of SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 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.
