The DG221BDY-T1 is a dual 8-channel Analog Multiplexer/Demultiplexer, which can be used in applications requiring the multiplexing or demultiplexing of analog signals. The part is ideal for applications where only a limited number of signals need to be multiplexed or demultiplexed, since it only requires a single chip. The DG221BDY-T1 is rated for operation up to 12V, and operates over a temperature range of -40°C to +85°C.
The DG221BDY-T1 includes two 8-channel switches, which are operated by two separate control pins. The part also includes an enable input pin that can be used to control the overall operation of the switch. The enable input sets the output of the part to either the high or low state, dependent upon the control signal present at the enable input.
The part features low on-resistance, low on-voltage, high off-isolation and low charge injection, thus making it ideal for use in applications such as telephone switching, data acquisition systems and power supply control. The part is available in a range of package styles including, single in-line, dual-in-line, surface mount and DIP, thus making it ideal for use in many different applications.
The DG221BDY-T1 has a very simple working principle. A multiplexer is a device which can select between multiple input signals and output one single output signal. The multiplexer consists of two control inputs and two selectors. The two control inputs allow the user to select between inputs, while the selectors determine whether the output of the part is connected to the high voltage or low voltage levels. The selectors determine which of the two inputs is being chosen, and passing that signal onto the output line.
The demultiplexer is the inverse of the multiplexer; it takes one input signal and outputs several different signals. In this case, the DG221BDY-T1 takes one input and outputs eight different signals. The demultiplexer also has two control inputs and two selectors, which again determine which of the two inputs is being chosen, and passing that signal onto the output lines.
In summary, the DG221BDY-T1 is a dual 8-channel Analog Multiplexer/Demultiplexer, which is ideal for applications requiring the multiplexing or demultiplexing of analog signals. The part is robust and reliable, offering low on-resistance, low on-voltage, high off-isolation, and low charge injection. It is available in a range of different package styles, and is thus suitable for a wide variety of applications.
