DG408LDQ-T1-E3 is a single-pole 8-throw (SP8T) analog switch multiplexer, designed to operate from a single 5V supply and is designed to drive wide range of analog signals. The device is offered in a 14-lead SOIC package and is guaranteed to meet the ESD and latch-up specifications listed in the datasheet. This provides excellent design flexibility in testing and debugging high speed data communications links within the electrical test environment.

The analog switch multiplexer consists of eight single-pole eight-throw (SP8T) switches, two independent two-input multiplexers, and two independent four-input multiplexers. Each switch is normally closed and has a parallel input bit and a digital control bit. The parallel input bit is the result of connecting multiplexed signals to the switch and is used to determine the switch settings based on the selected play mode. The control bit is used to activate the selected switch. The independent two-input multiplexers are used to select the play mode, allowing users to select either a serial or random play mode. Finally, the independent four-input multiplexers are used to control the speed of the multiplexed signal within a digital control environment.

The DG408LDQ-T1-E3 is ideal for applications requiring programmable analog signal control. It is commonly used in portable radio and television receivers for switching between phonograph inputs, stereos, tape decks, CD players and tuners. It is also frequently used in high performance telecommunications controllers for switching between data and audio signals. In addition, the device may be used for switching high speed data sources, such as in networking or Optical Network Terminal equipment. Finally, the device may be used for various medical instrumentation applications requiring analog signal control and switching between multiple analog sources.

The DG408LDQ-T1-E3 is easy to use and requires minimal effort to set up and configure, making it an ideal choice for all types of analog signal applications. The device also offers excellent thermal performance due to its low power, low bandwidth and very low switching distortion. In terms of its operating principle, the device works in conjunction with the controller to control the multiplexed signal by alternating between the two independent two-input multiplexers. When the controller sets the appropriate word enable signal, the output of the multiplexer can be routed into the output connection of the digital switch. The device then continues to switch between the two multiplexers, providing the user with complete control over the multiplexed signal.

The DG408LDQ-T1-E3 is an excellent choice for many analog signal applications due to its versatility and performance. It is easy to use and configure and delivers excellent thermal performance. The device features excellent signal integrity due to its wide bandwidth and low distortion, making it ideal for high speed signal control environments. The device is also ideal for applications requiring low power consumption and offers a great degree of flexibility in terms of signal routing and signal control. Finally, the DG408LDQ-T1-E3 is an excellent choice for a variety of analog signal control applications, including portable radios, television receivers, high performance telecommunications controllers, networking applications and medical instrumentation.
