The DG9421DV-T1-E3 (DG9421) is a high-speed, low-power, four-channel Analog Switches, Multiplexers, Demultiplexers. It is a single-chip solution that is used for analog signal switching and level conversion. The device is a single, integrated unit with up to four channels that can switch up to 240 μA current. The DG9421 provides single-pole, double-throw (SPDT) analog switching, which switches between high-to-low and low-to-high output logic levels.

The DG9421 has an operating voltage range of 2.7V to 5V, a maximum on-state resistance of 0.12 ohms, and a maximum off-state resistance of 1000 ohms, making it suitable for switching analog signals up to 5V in magnitude. The device also has a low input capacitance of 5pF, so it can also handle high-frequency signals, and has a propagation delay of 12ns.

The DG9421 has several important applications in the automotive and industrial field, including data and signal routing, machine vision, motion control, robotics, and more. The device is widely used to switch analog signals between analog and digital control systems, and can be used to route signals and control various system parameters. The device also has a tight tolerance on off-state resistance and wide range of operating voltages, which makes it suitable for use in many different applications.

The DG9421 works in two modes: continuous-conduction mode and single-shot mode. In continuous-conduction mode, the analog switches are enabled and control the analog reception continuously without any additional inputs. In single-shot mode, the user must provide an input signal to enable the analog switch, and then the switch will remain active until the input signal is removed. This is useful in applications where the user wants to switch the signal only when needed.

The DG9421 is a low-power, low-noise device with a low saturation voltage and wide voltage range. It is a single-chip solution that is ideal for applications such as motor control, active set-point control, load monitoring, and digital data routing. The device is highly reliable, with a maximum on-state resistance of 0.12 ohms and maximum off-state resistance of 1000 ohms.

To summarize, the DG9421 is a high-speed, low-power analog switches, multiplexers and demultiplexers. It provides single-pole, double-throw analog switching that can switch between high-to-low and low-to-high output logic levels. The device is suitable for switching analog signals up to 5V in magnitude. It has a low input capacitance of 5pF and a propagation delay of 12ns. The DG9421 has many applications in the automotive and industrial field, and is a highly reliable device with a maximum on-state resistance of 0.12 ohms and maximum off-state resistance of 1000 ohms.
