CD4067BE Typical application Circuitry

CD4067BE

CD4067BE is a 16-channel analog multiplexer/demultiplexer chip that allows the user to select one out of multiple analog signals for output, or to distribute one input signal to multiple outputs. This chip is highly versatile and widely applicable, especially suitable for scenarios requiring signal selection, such as data acquisition systems, signal switching, communication systems, and more.

Application Scenario:

A typical application scenario is in the expansion of analog inputs for a microcontroller. Since microcontrollers have a limited number of analog input channels, using CD4067BE can significantly expand the number of analog signals a microcontroller can handle, enabling it to process more analog inputs.

Parameter Features:

- Wide Operating Voltage Range: Typically between 10V and 20V, suitable for various power configurations.

- High Impedance: The high impedance at input and output ports ensures the quality of signal transmission and reduces loading effects.

- Low Power Consumption: It is perfect for applications that are power-sensitive because of its extremely low power consumption at standard temperature.

Specific Circuit Connection - Microcontroller Analog Input Expansion

Connection Overview: In this scenario, we will use CD4067BE to expand a microcontroller's analog input channels. Suppose our goal is to expand a microcontroller with limited analog inputs to be able to read up to 16 different analog signals.

1. Power Connection: Attach the CD4067BE's VSS pin to ground and its VDD pin to a positive power source. This gives the chip the operational voltage that it needs.

2. Microcontroller Interface: Choose four digital output pins from the microcontroller and connect them to the control input pins (S0 to S3) of CD4067BE. These control pins determine which signal channel is connected to the output of CD4067BE.

3. Analog Signal Input: Connect the analog signals you wish to read to the 16 input pins of CD4067BE (from C0 to C15). These pins are the input channels of the multiplexer.

4. Output Connection: Connect the output pin (SIG) of CD4067BE to one of the microcontroller's analog input pins. This way, the selected analog signal can be read by the microcontroller.

5. Ground Connection: Ensure that the ground of CD4067BE is connected to the microcontroller's ground to ensure consistency of the signal reference.

Issues to Consider

When Designing the Circuit:

- Signal Integrity: Ensure that signal paths are short and direct to reduce interference and maintain signal quality.

- Power Supply Filtering: Provide a stable power supply for CD4067BE, adding decoupling capacitors if necessary to reduce power noise.

- Preventing Overload: Ensure that signals connected to the input of CD4067BE do not exceed its maximum input voltage specification to avoid damaging the chip.

- Programming Control: Program the microcontroller correctly to ensure that the correct channel is selected, thereby reading the correct analog signal.

Through the above steps and considerations, CD4067BE can be effectively used to expand the analog input capability of a microcontroller, providing a simple and efficient solution for complex applications.
