Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Model Number: Breakout Board Module _x005f_x000D_ Analog Signal Input: C0-C15 16 Channels _x005f_x000D_ Analog Output: Dig _x005f_x000D_ Channel Control: S0-S3 _x005f_x000D_ Size: 41*17*3mm/1.61*0.67*0.12inch _x005f_x000D_ 1. This is a very useful breakout board for the 16-channel analog/digital multiplexer/demultiplexer CD74HC4067. _x005f_x000D_ 2. The chip is like a rotary switch - it internally routes the common pin (SIG) to one of the 16 channel pins (CHANxx). _x005f_x000D_ 3. Suitable for both digital and analog signals (voltage cannot be higher than VDC). _x005f_x000D_ 4. The connection works in both directions. _x005f_x000D_ 5. To control it, connect the 4 digital outputs to the selected chip address pins (S0-S3). _x005f_x000D_ 6. and send the binary address of the channel you want (see data sheet for details). _x005f_x000D_ 7. This allows you to connect up to 16 sensors to your system using only 5 pins. _x005f_x000D_ 8. Since the multiplexer/demultiplexer also works with digital signals, you can use it to connect up to 16 sensors to your system via a pipeline. _x005f_x000D_ You can use it to pipe TTL-level serial data to and from multiple devices. _x005f_x000D_ 9. TX lines from the microcontroller to the RX lines of up to 16 devices. _x005f_x000D_ 10. By using multiple cards, you can create a similar arrangement for I2C, SPI, etc. _x005f_x000D_ 11. Internal switches are bi-directional and support voltages between ground and VDC. _x005f_x000D_ 12. It has low resistance, low leakage, and switches off before on to prevent interference. _x005f_x000D_ 13. The board also destroys the chip's enable pin, which will completely disable the common pin (all switches) when driven high. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1*Analog Digital Multiplexer 1.Versatile: This analog digital multiplexer features the highly useful CD74HC4067, a high-speed CMOS analog multiplexer/demultiplexer with 16 channels. It acts like a rotary switch, internally routing the common pin (SIG) to one of the 16 channel pins (CHANxx). 2.Optimal Performance: This breakout board module is designed to handle both digital and analog signals, making it versatile for various applications. However, please ensure that the voltage of the signals does not exceed the specified limit (VDC) to maintain optimal performance. 3.Bi-Directional Operation: The analog multiplexer selector module can be controlled by connecting 4 digital outputs to the designated chip address pins (S0-S3). By sending the binary address of the desired channel (refer to the datasheet), you can easily select and route signals. This feature allows you to connect up to 16 sensors to your system using only 5 pins. 4.Compatible: Apart from analog and digital signals, this analog digital MUX breakout board also supports the transmission of TTL-level serial data between multiple devices. You can use it to route RX (receive) and TX (transmit) lines from a microcontroller to up to 16 devices. By using multiple boards, you can create similar arrangements for I2C, SPI, and other protocols.
