SN74CB3Q3251 is a low-voltage high-bandwidth bus switch from TI, with a working voltage range of 2.3V-3.6V and support for 0-5V signal levels.
The SN74CB3Q3251 is a 1-of-8 multiplexer/demultiplexer utilizing a charge pump to elevate the gate voltage of the pass transistor. This design provides a low and flat ON-state resistance, enabling minimal propagation delay and supporting rail-to-rail switching on data input/output ports. The device features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.
