This family of differential line receivers offers
improved performance and features that implement
the electrical characteristics of low-voltage differential
signaling (LVDS). LVDS is defined in the
TIA/EIA-644 standard. This improved performance
represents the second generation of receiver
products for this standard, providing a better overall
solution for the cabled environment. This generation
of products is an extension to TI's overall product
portfolio and is not necessarily a replacement for
older LVDS receivers.
