The SN74CB3Q3306APWR is a dual FET low-voltage high-bandwidth Bus Switch utilizes 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 SN74CB3Q3306A provides an optimized interface solution ideally suited for broadband communications, networking and data-intensive computing systems. It is organized as two 1-bit switches with separate OE (1OE\, 2OE\\) inputs. It can be used as two 1-bit bus switches or as one 2-bit bus switch. When OE\ is low, the associated 1-bit bus switch is ON and the A port is connected to the B port, allowing bidirectional data flow between ports.
