The SN74CB3Q3125 device is a high-bandwidth FET bus switch that uses a charge pump to elevate the gate voltage of the pass transistor, thus providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The SN74CB3Q3125 device also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.
