3.3V supply rail. Any of the four current mode
drivers will deliver a minimum differential output
voltage magnitude of 247mV into a 100Ω load
when enabled.
The intended application of this device and
signalling technique is for point-to-point baseband
data transmission over controlled impedance
media approximately 100Ω. 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 noise
coupling to the environment.

DESCRIPTION
The STLVDS31 is a quad differential line drivers
that implements the electrical characteristics of
low voltage differential signaling (LVDS). This
signaling technique lowers the output voltage
levels of 5V differential standard levels (such as
TIA/EIA-422B) to reduce the power, increase the
switching speeds and allows operations with a
The STLVDS31 is characterized for operation
from -40°C to 85°C.
