2.5V, 4:1, 11-channel analog multiplexer suitable for DDR-II applications

The SN74CBTU4411 device is a

high-bandwidth, SSTL18 compatible FET multiplexer/demultiplexer with low ON-state

resistance (ron). The device uses an internal charge pump to elevate the

gate voltage of the pass transistor, providing a low and flat ron. The

low and flat ron allows for minimal propagation delay and supports

rail-to-rail signaling on data input/output (I/O) ports. The device also features

very low data I/O capacitance to minimize capacitive loading and signal distortion

on the data bus. Matched ron and I/O capacitance among channels results

in extremely low differential and rising or falling edge skew. This allows the

device to show optimal performance in DDR-II applications.
