The DG418DY+ series of analog multiplexers are dual 4 x 1 Muxers that utilize E-series switching arrangements for several internal design features. They are perfect for applications such as stereo parameter selection or any application requiring selecting one of several input sources to a single output. Designed mainly for consumer and professional audio applications, but can be found in many other types of applications such as medical, telecom and test & measurement.

The DG418DY+ series multiplexers are CMOS logic devices that are easy to use and provide reliable operation with a very low operating current and have wide output voltage swing. The device is available in a 16-lead Plastic Small Outline Package that is RoHS compliant and has a high performance, high efficiency CMOS design.

The DG418DY+ series has high off-isolation between channels, input switches, high slew rate and low power consumption. Additionally, the device features an internal ESD protection, a lockout bar to disable unused channels, and an E-series operating mode for superior isolation, as well as data sheet-specified temperature drift and power supply rejection ratio specification. This series of devices also feature an adjustable logic threshold input and low impedance outputs.

The working principle behind the DG418DY+ series of analog multiplexers is relatively simple. Essentially, each device uses a series of E-series switches that are connected to the inputs and can be set to either a high or low position. These switches can be used to select one of the several input sources and direct it to a single output. For example, if a user wants to select a specific stereo parameter such as volume or treble, they could simply set the E-series switch to the desired input and the output will be set accordingly.

In addition, this series of devices also features several other features that are designed to make them more reliable and efficient. Some of these features include an adjustable logic threshold input and low impedance outputs, as well as ESD protection and a lockout bar to disable unused channels. Additionally, the DG418DY+ series has a high slew rate and low power consumption.

Overall, the DG418DY+ series of analog multiplexers are ideal for applications such as stereo parameter selection or any application requiring selecting one of several input sources to a single output. These devices are easy to use and provide reliable operation with a very low operating current and wide output voltage swing. The internal ESD protection, lockout bar to disable unused channels, and adjustable logic threshold input and low impedance outputs further enhance their functionality and make them well suited for a variety of applications.
