description
The SN65LVDM31 incorporates four differential
line drivers that implement the electrical charac-

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

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.
