DG442LDY-T1-E3 is a Analog Switch, Multiplexer, Demultiplexer product, which is offered from International Rectifier (which is part of Infineon Technologies). This product is focus on providing circuit designers with an high-frequency multiplexer that is able to easily work with analog signals in automotive applications. The DG442LDY-T1-E3 analog switch, multiplexer and demultiplexer is designed to provide reliable high-frequency routine shifting capabilities in a small package.

This product is composed of 6 PINs, including 4 a/b switch inputs, 1 ground terminal and a b/c output. It offers a wide range of applications and control inputs. The typical operation of the DG442LDY-T1-E3 is defined by a feedback control circuit which switches the output between two or more inputs (or vice versa). The output line is selected by the a/b inputs using differential logic. Additionally, the device allows for the differential logic to be lifted through an asynchronous reset (RESET) pin.

The DG442LDY-T1-E3 supports logic levels from -0.3 to +12V with a TTL logic threshold from 3V to 5V. It provides a low capacitance up to 5 pF across its channels with a minimum off-state leakage of 100nA. It offers a low on-state resistance of 0.4Ω with a low crosstalk of -60 dB. The device also offers a fast switching time of less than 6ns, making it one of the fastest multiplexers on the market today.

The device has a maximum RMS voltage rating of 30V and a maximum peak voltage rating of 40V. It is capable of operating over a temperature range of -55°C to +125°C, making it well-suited for automotive applications. Additionally, the product is RoHS compliant, making it an environmentally friendly choice and a good candidate for many application designs.

The DG442LDY-T1-E3 works by providing a differential logic input from two logic-level inputs and switching the output accordingly. The device has two analog inputs and one output. The two inputs and the output are connected together in a specific configuration (defined by the manufacturer) that allows for the high-frequency multiplexer to function in this way. The reset pin is also connected to one of the logic inputs and is used to control the state of the multiplexer.

This product is ideal for automotive applications with its high-frequency multiplexing capabilities, small package, fast switching time and low capacitance. It is an excellent choice for many circuit design projects. This product provides reliable and robust switching capabilities, along with an environmentally friendly design and multiple control options.
