SN74CB3Q32245 32 位总线开关 2.5V/3.3V 高带宽
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 (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 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
