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

Improved features include an input common-
mode voltage range 2 V wider than the minimum
required by the standard. This will allow longer
cable lengths by tripling the allowable ground
noise tolerance to 3 V between a driver and
receiver.
