The MAX4742EUA+T, a CMOS analog switch, multiplexer, and demultiplexer, is manufactured using the CMOS process from Maxim Integrated. It operates from a single +2.7 to +5.25V supply, making it suitable for a variety of applications that require low-voltage power supplies. The MAX4742EUA+T has a TTL/CMOS-compatible logic interface that enables up to 8 different analog signals to be multiplexed into two analog ports. The MAX4742EUA+T features fast switching times of < 40ns, low charge injection of < 4pC, and low current leakage of < 10nA at +25°C. With a 2.7V to 5.25V supply voltage, the MAX4742EUA+T is suitable for multiple applications requiring low-voltage operation, such as medical imaging, mobile devices, and automotive electronics.

The eight inputs of the MAX4742EUA+T can be multiplexed into two output ports by the SELECT input. The SELECT input is a single-ended signal that chooses which of the eight inputs will be connected to each of the two outputs. The SELECT input can also be used to select between two shutdown modes: in Shutdown Mode 0 the two outputs are shut down and in Shutdown Mode 1 the inputs are shut down. The OPEN4# and OPEN2# inputs are used to programmatically disconnect the respective four or two analog switch inputs to allow the user to enter a known state.

The MAX4742EUA+T has wide analog input ranges of +2.7V to +5V. This allows the input signals to have a wider dynamic range. Additionally, the fast switching time of < 40ns ensures that signals are switched quickly and accurately. Low charge injection of < 4pC helps prevent signal distortion due to discharge of the capacitor when the switch is turned off. Finally, the low leakage current of < 10nA helps reduce power consumption and helps preserve signal accuracy.

The MAX4742EUA+T is an ideal solution for applications such as Patient Monitoring and Diagnostic Imaging. The MAX4742EUA+T\'s low supply voltage and its ability to multiplex multiple signals into two analog ports simplify the design process. This multiplexer is also suitable for wireless communication systems, such as those used in automotive and aerospace applications, as it can handle multiple reception and transmission channels with a single IC.

In summary, the MAX4742EUA+T is an ideal device for applications that require low-voltage operation, fast switching times, low charge injection, and low leakage current. With the high input dynamic range and TTL/CMOS-compatible logic interface, the MAX4742EUA+T is an ideal solution for multiplexing multiple signals into one or two analog ports.
