Feature summary
Description
The STLVDS3487 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 3.3V supply rail. Any of the four
current mode drivers will deliver a minimum
differential output voltage magnitude of 247mV
into a 100 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 100 . 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.
The STLVDS3487 is characterized for operation
from -40°C to 85°C.
