Working Principles

The MAX4645EUT-T is an analog switch that allows or blocks the flow of signals between its input and output terminals. It operates based on the control voltage applied to the input pin (IN). When the control voltage is high, the switch is turned on, allowing the signal to pass through from the input (IN) to the output (NO) terminal. Conversely, when the control voltage is low, the switch is turned off, blocking the signal flow.
