description/ordering information  
The SN74CB3Q32245 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 SN74CB3Q32245 provides an optimized  
interface solution ideally suited for broadband communications, networking, and data-intensive computing  
systems.  
The SN74CB3Q32245 is organized as four 8-bit bus switches with separate output-enable (1OE, 2OE, 3OE,  
4OE) inputs. It can be used as four 8-bit bus switches, two 16-bit bus switches, or as one 32-bit bus switch. When  
OE is low, the associated 8-bit bus switch is ON and the A port is connected to the B port, allowing bidirectional  
data flow between ports. When OE is high, the associated 8-bit bus switch is OFF, and a high-impedance state  
exists between the A and B ports.
