description/ordering information  
The SN74CB3Q3306A is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage  
of the pass transistor, providing a low and flat ON-state resistance (r ). The low and flat ON-state resistance  
on  
allows for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The  
device also 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  
optimized interface solution ideally suited for broadband communications, networking, and data-intensive  
computing systems.
