Texas Instruments  SN74CBTU4411ZSTR

The SN74CBTU4411 device is a high-bandwidth, SSTL_18 compatible FETmultiplexer/demultiplexer with low ON-state resistance (ron). The deviceuses an internal charge pump to elevate the gate voltage of the pass transistor, providing a lowand flat ron. The low and flat ron allows for minimalpropagation delay and supports rail-to-rail signaling on data input/output (I/O) ports. The devicealso features very low data I/O capacitance to minimize capacitive loading and signal distortion onthe data bus. Matched ron and I/O capacitance among channels results inextremely low differential and rising or falling edge skew. This allows the device to show optimalperformance in DDR-II applications.
