DG612DJ-E3 are high performance, low power, CMOS analog multiplexers/demultiplexers with ESD protection that allows very low current drain and the unique features of fast switching, low ON resistance and low OFF leakage. The device is a monolithic CMOS device with a 5V supply that is capable of providing low-noise signal level conversion up to 32V. It has extended temperature range and is designed for applications for switching and multiplexing of single-ended signals.

The device has an integrated ESD protection circuit and can be used for signal path switching. The input protection circuit consists of a 10kΩΩ resistive termination in line with the supply voltage terminal, which provides a high degree of protection from static discharges. The ESD protection circuit isolates the analog input from the control logic and prevents unexpected device failures. The device also features over voltage protection on the control inputs to prevent unintentional switching when the control voltage exceeds the supply.

DG612DJ-E3 can be used in a wide range of applications including audio, video, industrial and automotive applications. It can also be used for driving capacitive loads, such as display devices, without generating EMI noise. Furthermore, the device is ideal for RF applications as it supports high speed switching and low signal distortion.

The working principle of the DG612DJ-E3 is simple. It has 8 CMOS switches arranged in a 4-by-4 array. Each switch can be independently controlled by 8 control logic inputs. The device can be controlled in multiple ways including a shift register, latched data, or via a combination of latched data and multiplex address signals. Through the control inputs, one of the four inputs is connected to the common output signal. Each input is connected to the output via one of the four wide signal buses.

Each switch has an internal resistance of 4.2 Ω and provides low power losses. The operating signal range is up to 32V. The input protection circuit is designed to ensure that small signal offset errors are not amplified. The die also has ESD protection diodes to protect the inputs/outputs and to prevent latch-up.

In summary, DG612DJ-E3 are high performance, low power, CMOS analog multiplexers/demultiplexers with ESD protection that allows very low current drain and the unique features of fast switching, low ON resistance and low OFF leakage. It can be used for a wide range of applications including audio, video, industrial and automotive applications. The device is capable of providing low-noise signal level conversion up to 32V and is ideal for RF applications as it supports high speed switching and low signal distortion.
