Working Principles

The MAX244C/D is an analog multiplexer and demultiplexer integrated circuit. It operates by selectively connecting one of the four input channels to the output channel based on the control signals applied to the selection pins (S0-S3). The enable pin (EN) activates the device, allowing the selected input to pass through to the output. The high-speed operation and low on-resistance ensure minimal signal degradation and distortion during transmission.
