DESCRIPTION

The LX5245/5246/5247 ICs are Low Voltage Differential (LVD) Terminators designed to comply with the LVD termination specification in the SPI-2 document. The LX5245/5246/5247 are designed specifically for LVD applications. Because the LX5245/ 5246/5247 support only LVD, they have lower output capacitance than multimode terminators such as the LX5240.
