The SN65LVDM31 incorporates four differential
line drivers that implement the electrical charac-
teristics of low-voltage differential signaling. This
product offers a low-power alternative to 5-V
PECL drivers with similar signal levels. Any of the
four current-mode drivers will deliver a minimum
differential output voltage magnitude of 540 mV
into a 100-Ω load when enabled by either an
active-low or active-high enable input.

The intended application of this device and
signaling technique is for both point-to-point and
multiplexed 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 and the noise coupling to the environment.
The SN65LVDM31 is characterized for operation from –40°C to 85°C.

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.
NOTES: 1. All voltage values, except differential I/O bus voltages, are with respect to network ground terminal.
2. Tested in accordance with MIL-STD-883C Method 3015.7.
