DESCRIPTION
This 10-bit bus switch is designed for 2.3 V to 2.7 V VCC operation and SSTL_2 select input levels. Each Host port pin is multiplexed to one of four DIMM port pins. When the S pin is low the corresponding 10-bit bus switch is turned on. The on-state connects the Host port to the DIMM port through a 20 Ω nominal series resistance. When the S pin is high the switch is open and a high-impedance state exists between the two ports.
