The CD4053BEG4 is a monolithic, high speed CMOS device with three ultra low-on-resistance analog switches and three digital control inputs that select an analog signal path. It is an ideal device for multiplexing and demultiplexing applications. Designed with superior performance characteristics of low impedance, high on/off isolation, and low noise and distortion, the CD4053BEG4 is ideal for dynamic signal switching.

Application Fields

The CD4053BEG4 has a wide variety of applications in the fields of communications, instrumentation, robotics, automotive, and avionics.

The device can be used as a digital-to-analog switch, a differential analog gate and as an analog multiplexer and demultiplexer. It also has applications in analog to digital converters, video routing, power supplies and video processing.

Working Principle

The CD4053BEG4 consists of three CMOS switches controlled by three binary coded select inputs. Each switch can be individually connected to one of two signal paths, depending on the logic state of the select inputs. The crosstalk and feedthrough between input and output signal paths are minimized by the low impedance levels provided by the CMOS technology.

The CD4053BEG4 has an enable input which will turn off all the switches when this input is at a low logic level. This makes the device suitable for use as a digital transmission switch. It also has very low power consumption, making it ideal for portable applications.

Each switch also has an internal resistance which limits the current that can be passed through it. This internal resistance can be addressed by using a voltage follower. As a result, the CD4053BEG4 can be used in low-impedance applications without requiring extra components or power supply voltage levels.

The CD4053BEG4 has high precision switching properties. The on-state resistance is matched between switches and high on/off isolation is achievable. The device is also fast switching and can provide switching speeds of up to 4ns. This enables the device to be used in high-speed applications such as switching between multiple inputs with minimal distortion.

Overall, the CD4053BEG4 is a reliable and versatile device that can be used in a wide variety of applications. It has excellent switching characteristics, low power consumption and fast switching speeds. It is well suited for use in both low- and high-impedance circuits. This makes it an ideal choice for multiplexing and demultiplexing applications.
