Bus Switch 2-Element CMOS 2-IN 8-Pin VSSOP T/R

The SN74CB3Q3306 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage ofthe pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allowsfor minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The devicealso features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.Specifically designed to support high-bandwidth applications, the SN74CB3Q3306A provides an optimizedinterface solution ideally suited for broadband communications, networking, and data-intensive computingsystems.
