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.
This generation 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. TI has additionally introduced an even
wider input common-mode voltage range of –4 to
5 V in their SN65LVDS/T33 and SN65LVDS/T34.
