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 (ron). The low and flat ON-state resistance 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.  
PRODUCTION DATA information is current as of publication date.  
Copyright © 2003–2005, Texas Instruments Incorporated  
Products conform to specifications per the terms of the Texas  
Instruments standard warranty. Production processing does not  
necessarily include testing of all parameters.
