CD4051BDTR

The CD4051BDTR is a high-performance, digitally controlled analog switch that functions as an 8-channel multiplexer or demultiplexer. This versatile device is designed to route analog signals with low ON impedance and very low OFF leakage currents, making it ideal for a wide range of applications.

Key Specifications and Features

• 8-Channel Configuration:

  • The CD4051BDTR offers eight independent input/output channels (Y0-Y7), each of which can be selectively connected to a common input/output terminal (Z) under digital control.

• Digital Control:

  • The device is controlled by three binary address inputs (A0, A1, A2) and a low-active enable input (E). The combination of these inputs allows for the selection of one of the eight channels to be turned on and connected to the common terminal.

• Low ON Impedance and Low OFF Leakage:

  • The CD4051BDTR exhibits low ON impedance, ensuring minimal signal loss during transmission. Additionally, the OFF leakage currents are very low, preventing unwanted signal interference when the switches are off.

• Wide Operating Voltage Range:

  • The device can operate with a supply voltage range of 3V to 9V (VDD-VSS), providing flexibility in designing circuits with different voltage requirements.

• High-Speed Switching:

  • The CD4051BDTR supports high-speed switching, making it suitable for applications that require rapid signal routing or multiplexing.

• Compact Package:

  • The device is available in a SOP-16 package, which is compact and easy to integrate into printed circuit boards.

• Robust Performance:

  • The CD4051BDTR offers high reliability and stability, ensuring consistent performance over a wide range of operating conditions.

Applications

• Analog Signal Routing:

  • The CD4051BDTR can be used to route analog signals in various applications, such as audio/video systems, data acquisition systems, and test equipment.

• Multiplexer/Demultiplexer Functions:

  • The device can function as an 8-channel analog multiplexer, allowing multiple analog signals to be selectively connected to a single output. Conversely, it can also operate as a demultiplexer, distributing a single analog signal to one of eight outputs.

• Digital-to-Analog Interface:

  • The CD4051BDTR can be used in digital-to-analog interface circuits, where digital control signals are used to select and route analog signals.

In summary, the CD4051BDTR is a versatile and high-performance 8-channel analog multiplexer/demultiplexer that offers low ON impedance, low OFF leakage currents, and a wide operating voltage range. Its compact package and robust performance make it an excellent choice for a wide range of analog signal routing and multiplexing applications.
