CMOS 8-Channel Analog Multiplexer/Demultiplexer – NTE4051B

Product Overview

The NTE4051B is an advanced CMOS 8-channel analog multiplexer/demultiplexer designed to efficiently route analog or digital signals in complex circuits. Featuring a single-pole 8-throw (SP8T) configuration, this IC allows selection of one of eight input/output lines through binary address inputs, enabling flexible signal management for a wide range of electronic applications.

Features and Technical Specifications

• CMOS integrated circuit with low power consumption
• 8-channel (8:1) analog multiplexer/demultiplexer
• Single device per package (QTY per package: 1)
• SP8T switching – connects one of eight channels to a common terminal
• Compatible with standard CMOS logic levels
• Supports analog and digital signal switching

Applications

• Analog signal routing and switching
• Data acquisition systems
• Multiplexed sensor interfacing
• Industrial control panels
• Test instrumentation
• Audio/video source selection

Operation and Controls

Channel selection is performed by applying a 3-bit binary code to the address inputs, allowing direct control of the active channel. The common terminal can be used as either an input or output, while the eight remaining terminals serve as selectable signal paths.
