The device consists of four high-speed CMOS multiplexers and four binary decoders and control logic. The switch matrix is formed with 4 rows and 4 columns and is used for routing and switching of analog signals. It supports true signal style switch and can be enabled/disabled through CMOS logic. The plus point of this device is that the timing and setup are independent of each other and are independent of the supply voltage level.
The internal multiplexers are controlled by the four binary select lines A, B, C and D. The ON/OFF switches of the matrix are also controlled by the four binary select lines. Each row of the matrix is individually enabled by the RS Macrocell. This is further supported by the control logic which is used to control the switching of each column of the matrix.
The device works on three basic principles, the multiplexing of the signal, the switching of the signal and the controlling of the signal. The multiplexing process entails the inputting of one individual signal and the outputting of multiple selections of the signal through different combination of the select inputs. This allows for the routing and direction of the desired signal.
The switching of the signal requires the use of the switch matrix. The mechanical combination of the columns and rows allows the selection of one particular signal and switching it to the desired output. This selection effectively isolates the other signals while allowing the being of a clear and efficient signal.
The control logic is the key to the operation of the DG2742DS-T1-E3 device. This logic is programmed for the working environment and establishes the control of the switch matrix and the multiplexing function itself. It also monitors the power levels and voltage ranges, ensuring there are no spikes to cause any damage to the device.
In summary, the DG2742DS-T1-E3 device is a highly efficient interface which is used for the purpose of multiplexing and routing of analog signals. It is suitable for industrial and automotive applications, due to its low quiescent current. Its operates based off of three principles, the multiplexing, the switching and the control logic, to produce high-quality signals without any loss in power or voltage.
