Working Principles

The SN74CB3Q3253PWRE4 is based on CMOS technology, which allows for low-power operation. It consists of two independent multiplexers/demultiplexers that can be controlled using the S0 and S1 pins. The OE# pin is used to enable or disable the output. When the OE# pin is low, the outputs are active, and when it is high, the outputs are in a high-impedance state.

The IC uses a combination of MOSFETs and transmission gates to achieve bidirectional signal switching. These components ensure minimal signal distortion and low on-state resistance, allowing for efficient signal routing.
