3 Description

This family of 4, 8, and 16 differential line drivers

implements the electrical characteristics of lowEIA/

voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5-V

differential standard levels (such as EIA/TIA-422B) to

reduce the power, increase the switching speeds, and

allow operation with a 3.3-V supply rail. Any of the 16

current-mode drivers will deliver a minimum

differential output voltage magnitude of 247 mV into a 100-Ω load when enabled.
