The DG419AK/883B is a CMOS analog multiplexer/demultiplexer. As an analog switch, it contains 16 independent switches with low on-resistance values. The device operates over a wide voltage range, from 2.7V to 18V. It provides good isolation between channels. The device is ideal for applications where low on-resistance accuracy and high switching speed are required.

The DG419AK/883B multiplexer/demultiplexer is suitable for a wide range of applications such as data acquisition, communication systems, video signal processing, analog and digital signal conditional, system control, and test and measurement. The device can be used to select one of several input signals and route it to one output. This is important for applications where multiple input signals need to be sequentially accessed, as in digital to analog (D/A) and analog to digital (A/D) converters.

The DG419AK/883B multiplexer/demultiplexer operates in two different modes: single-ended and differential. In single-ended mode, the input voltage can range from -2.7V to +18V, and the output voltage can range from 0V to +18V with a maximum output voltage swing of 14V. In differential mode, the common mode voltage range is -1V to +15V, and the output voltage can range from -7V to +7V with a maximum output current swing of 10mA.

The DG419AK/883B multiplexer/demultiplexer operates by controlling four select pins (EN1-EN4). These pins are used to select which input signal is routed to the output by connecting the corresponding inputs. The device also includes four enable pins (A-D). When these pins are low, the device is enabled and the selected input is routed to the output. When the enable pins are high, the device is disabled and the output is open.

The DG419AK/883B multiplexer/demultiplexer has a wide bandwidth of up to 500MHz and a fast switching speed of 12ns. The device is designed to use low power, with a typical supply current of only 5mA. The device also has an integrated thermal protection to prevent damage from over-temperature conditions.

In summary, the DG419AK/883B multiplexer/demultiplexer is a versatile analog switch with high performance and low power consumption. With its fast switching speed and wide bandwidth, it is suitable for a wide range of applications including data acquisition, communication systems, video signal processing, analog and digital signal conditioning, system control, and test and measurement. The thermal protection ensures safe operation in extreme conditions.
