Please kindly noted that this item is sold by Jundayo from Joybuy marketplace. Origin: Mainland China _x005f_x000D_ Condition: New _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: 1*Analog Digital Multiplexer Low Resistance & Low Leakage: The internal switches of this analog digital multiplexer board are bidirectional, allowing bi-directional signal flow. They have low resistance, low leakage, and support voltage between ground and VDC. Additionally, the switching is designed to prevent interference. The board also features an enable pin that completely disables the common pin (all switches) when driven high, providing additional control and convenience. 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. 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. 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. 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).
