description/ordering information  
The SN74CB3Q3253 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 SN74CB3Q3253 provides an optimized  
interface solution ideally suited for broadband communications, networking, and data-intensive computing  
systems.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
