SN74CB3Q3125 Datasheet (Texas Instruments)

SN74CB3Q3125, Quadruple FET Bus Switch

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 switchin
