Key Features
- 8-channel single-ended analog multiplexer/demultiplexer with low on-resistance, enabling precise signal routing across multiple input/output channels in a single 16-pin DIP package
- High-speed CMOS design with wide analog signal voltage range, allowing both digital control and analog signal switching without signal degradation in mixed-signal applications
- Through-hole 16-pin DIP package for simple PCB integration and prototyping, with break-before-make switching action that prevents channel-to-channel short circuits during transitions
Applications
The CD74HC4051E-NG is commonly used in data acquisition systems, instrumentation, and audio signal routing where multiple analog signals must be selectively connected to a single input or output. It is well-suited for use in audio mixers, sensor multiplexing in embedded systems, and test equipment where controlled switching of analog voltages is required. The CMOS architecture ensures minimal power consumption and broad compatibility with both 3.3V and 5V digital control logic.

Frequently Asked Questions
How many channels does the CD74HC4051E-NG support and how are they selected?
The CD74HC4051E-NG supports 8 single-ended analog channels, selected via 3 binary address inputs (S0, S1, S2). The binary code on these pins determines which of the 8 channels is connected to the common input/output, enabling straightforward digital control of analog signal routing in multiplexer or demultiplexer mode.
Can the CD74HC4051E-NG handle both digital and analog signals?
Yes, the CD74HC4051E-NG is designed to switch analog signals under digital control. Its CMOS bilateral switches can pass analog voltages across a wide range, making it suitable for audio, sensor, and general-purpose analog signal routing in mixed-signal systems where both digital control logic and analog signal paths are present.
What package does the CD74HC4051E-NG come in and is it breadboard compatible?
The CD74HC4051E-NG comes in a 16-pin DIP (Dual In-Line Package), which is directly breadboard compatible and ideal for through-hole PCB assembly. This makes it an excellent choice for prototyping data acquisition systems, signal routing circuits, and educational electronics projects.
What supply voltage range is supported by the CD74HC4051E-NG?
The CD74HC4051E-NG operates over the standard HC-series supply voltage range of 2V to 6V, supporting both 3.3V and 5V digital systems. The analog signal range extends from the negative supply (VEE) to VCC, allowing versatile analog signal handling across common logic supply levels.
