The CD74HC4052NSRG4 is an integrated circuit that provides a multiplexer/demultiplexer, otherwise known as an analog switch. It is part of the family of CMOS logic-level analog and digital switch/multiplexer integrated circuits from Texas Instruments, the global leader in semiconductor design and manufacturing. The CD74HC4052NSRG4 offers an optimal combination of high speed, low power consumption and low voltage operation for general applications.

This multiplexer/demultiplexer switch is primarily used to route or switch analog or digital signals between several sources, making it a versatile interface for biomedical devices, data acquisition, test and measurement applications. It also finds application in sensors and mobile devices. The switch is tri-state, so it can be used to multiplex several analog signals, or to isolate and protect one circuit from another.

The CD74HC4052NSRG4 is a dual 4-channel multiplexer/demultiplexer with independent enable pins. It features a differential input and output, allowing it to switch a wide range of voltage levels. The output is designed to handle up to 1.2V peak-to-peak voltage. Its input resistance is also designed to be low and its on-resistance is designed to be low, thus reducing cross-talk. Additionally, the IC has envelope detectors, sample and hold amplifiers and ac removers. The on-resistance is usually very low, making it suitable for switching low-level voltages and currents.

The switch has two control signals, one for each channel. These signals can be used to enable or disable the channel and choose between the multiplexer and demultiplexer. The IC also has an “enable switch” pin, which when enabled can be used to set the state of the switch. It also has an “off-state”, which can be used to keep the logic voltage level high and the current flow low, effectively eliminating the possibility of spurious conduction. The on-resistance is low, reducing the effect of static power supply, noise and glitches on the circuit.

The CD74HC4052NSRG4 operates at temperatures ranging -40 degree Celsius to 85 degree Celsius and can be powered with a supply voltage ranging from 1.65Vdc to 5.5Vdc. It is available in standard JEDEC SOIC-8 and TSSOP-8 packages and is compliant with the following standards: JEDEC/Moisture Sensitivity Level (MSL), EIAJ/JIS (TOSH) Electronic Industries Alliance of Japan, and CECC (Council of European Committees for Electrotechnical Standardization) standards.

In summary, the CD74HC4052NSRG4 from Texas Instruments is a dual 4-channel multiplexer/demultiplexer that offers the optimal combination of high speed, low power consumption, and low voltage operation for general applications. It has envelope detectors, sample and hold amplifiers and ac removers. It is suitable for switching low-level voltages and currents and can also be used for digital signal routing or isolation. It operates at temperatures ranging from -40 degree Celsius to 85 degree Celsius and can be powered with a supply voltage of 1.65Vdc to 5.5Vdc.
