The CD74HC4052EG4 analog multiplexer/demultiplexer is an integrated circuit designed to switch multiple analog signals through a single output channel. The device can be used to select one analog signal from two different sources. It has two analog inputs, two digital inputs and one output. It operates on a 5V DC power supply.

The CD74HC4052EG4 multiplexer/demultiplexer is used in a wide variety of applications, including audio/video switching, automotive testing, industrial test and measurement, instrumentation and process control, and telecom infrastructure. In these applications, the device can be used to select an analog signal from two different sources and output it on a single channel.

The device can be used in either single-pole single-throw (SPST) or single-pole double-throw (SPDT) switch configurations. It is a high-speed, TTL-compatible switching device that provides excellent off-isolation and low insertion loss. The device includes low on-resistance and can drive up to 30 mA. It features ESD protection for improved reliability.

The working principle of the CD74HC4052EG4 multiplexer/demultiplexer is based on a combinational logic circuit. The device has two select (SEL) inputs, two control (CTRL) inputs, and two analog inputs (A1 and A2). The SEL inputs select the desired input to be sent to the output. The CTRL inputs control the direction of the switch, i.e., whether the A1 or A2 input is sent to the output. When the CTRL inputs are both active (high or low), the output is high impedance (Hi-Z).

The device is packaged in a small 8-pin plastic SOIC package, making it ideal for use in space- and cost-constrained applications. It is rated for operating temperatures from -40°C to 85°C and is available in both commercial and industrial grades.

The CD74HC4052EG4 multiplexer/demultiplexer is a versatile and reliable device that is suitable for a wide range of analog signal switching applications. It is widely used in automotive, industrial, instrumentation and process control applications to select and switch analog signals from two distinct sources. Its small size and low power requirements make it an ideal choice for cost-sensitive and space-constrained applications.
