Specifications: Operation Voltage: 2V to 6V "On" Resistance: 70 Ohms @ 4.5V Break-Before-Make Time: 6ns @ 4.5V Operating Temperature Range: -50℃ to 125℃ Features: This is a breakou t board for the versatile 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. Operates like a rotary switch, internally routing the common pin to one of 16 channel pins (CHANxx). Compatible with both digital and analog signals (maximum voltage equal to VCC) with bidirectional connections. Control the chip by connecting 4 digital outputs to the address select pins (S0-S3) and use the binary address of the desired channel. Connect up to 16 sensors to your system using only 5 pins! Ideal for piping TTL-level serial data to or from multiple devices. Example Application: Connect TX pins of 16 devices to a microcontroller's RX pin. Select any of the 16 devices to listen to. For two-way communication, add a second board to route the microcontroller's TX line to 16 device's RX lines. Create configurations for I2C, SPI, and more using multiple boards. Internal switches are bidirectional, supporting voltages between ground and VCC. They feature low "on" resistance and low "off" leakage, with "break-before-make" switching to avoid crosstalk. The board includes a breakout for the chip's "enable" pin, which fully disconnects the common pin when driven high, turning off all switches.
