The DG411DJ-E3 is a device belonging to the Interface – Analog Switch, Multiplexer, Demultiplexer family. This device is an operational dual 4:1 analog multiplexer/demultiplexer. It has two independent, 4:1 multiplexers/demultiplexers contained in a single package, controlled by a single logic input marked EN.

Application Field

The DG411DJ-E3 can provide the benefits of an analog switch or multiplexer/demultiplexer with low power, low cost and minimum space requirements. The device can operate in environments that require high speeds, low on-resistance and low leakage. As a result, it is widely used in automotive and industrial applications such as hand-held computers, battery-powered systems, such as automatic meter reading and portable medical equipment, as well as laboratory test equipment.

Working Principle

The DG411DJ-E3 consists of two independent 4:1 multiplexers/demultiplexers with a total of eight channels, each with an independent enable. Each multiplexer/demultiplexer has four differential inputs, one differential output and an internal gain-stage FET switch. The differential input and output pins are D0- D3 and D4 -D7. The enable pins are EN0 and EN1. When enable pin EN is high, the multiplexer/demultiplexer operates in the multiplexer mode, i.e. the differential outputs D4-D7 are connected to the differential inputs D0-D3 in the sequence set by the binary code of the address pins A0-A1. When enable pin EN is low, the multiplexer/demultiplexer operates in the demultiplexer mode, i.e. the differential input D4-D7 is connected to the differential output D0-D3 in the sequence set by the binary code of the address pins A0-A1.

The DG411DJ-E3 has excellent analog performance characteristics, including low on-state resistance, low off-state leakage, low cost, and extremely low power consumption. The device provides five types of switching configurations, including: single-pole, dual-pole, quad-pole, octal-pole and ultra-high speed (UHS) configuration. The switching speed of the device is also optimized with a maximum on-state resistance of 5Ω, a maximum on-state capacitance of 1pF and a low off-state leakage of 0.1nA. Additionally, the device is housed in an industry-standard 16-pin, dual in-line (DIP) package for improved thermal dissipation, and has an operating temperature range of -40 to 85 °C.

Conclusion

The DG411DJ-E3 is a versatile and reliable device belonging to the Interface – Analog Switch, Multiplexer, Demultiplexer family. With its wide range of applications and excellent performance characteristics, the DG411DJ-E3 is a must-have device for any automotive or industrial application requiring a cost-effective and space-saving solution.
