The SN74CB3Q3253 device is a high-bandwidth FET bus switch using a charge pump to elevatethe gate voltage of the pass transistor, providing a low and flat ON-state resistance(ron). The low and flat ON-state resistance allows for minimal propagationdelay and supports rail-to-rail switching on the data input and output (I/O) ports.
