description/ordering information
The SN74CB3Q3244 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 SN74CB3Q3244 provides an optimized
interface solution ideally suited for broadband communications, networking, and data-intensive computing
systems.
