DESCRIPTION/ORDERING INFORMATION

The SN74CB3Q3305 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_on). 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 SN74CB3Q3305 provides an optimized

interface solution ideally suited for broadband communications, networking, and data-intensive computing

systems.

The SN74CB3Q3305 is organized as two 1-bit switches with separate output-enable (1OE, 2OE) inputs. It can

be used as two 1-bit bus switches or as one 2-bit bus switch. When OE is high, the associated 1-bit bus switch is

ON and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is low, the

associated 1-bit bus switch is OFF and a high-impedance state exists between the A and B ports.
