National Semiconductor was involved in the development of the MLVDS standard. The backbone of the standard has been written around the BLVDS devices from National that has been used so effectively for over 5 years. The MLVDS standard has added an additional specification to increase the input common mode range. BLVDS devices can operate in applications where the ground potential between devices is up to a volt apart. The MLVDS devices additional common mode range will allow them to operate in applications where the ground difference is up to 2 volts apart.
