SN74CB3Q3253 双路 4 选 1 FET 多路复用器/多路解复用器，2.5V/3.3V 低电压高带宽总线开关
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.
The SN74CB3Q3253 is organized as two 1-of-4 multiplexers/demultiplexers with separate output-enable (1OE\, 2OE\) inputs
