What are the key features of CD74HC4351EE4?

  • 8-channel analog multiplexer/demultiplexer with 180 MHz bandwidth for high-frequency signal routing
  • Wide supply range from 2 V to 10 V (VCC-VEE) supporting both single-supply and dual-supply configurations
  • Single-ended architecture in 20-pin DIP package for easy breadboard prototyping and through-hole PCB integration

What is CD74HC4351EE4 used for?

The CD74HC4351EE4 is designed for high-speed analog signal switching in data acquisition systems, audio routing matrices, and instrumentation front-ends where multiple channels share a single ADC or processing path. Its 180 MHz bandwidth accommodates RF-adjacent and video-frequency signals, while the wide supply voltage range enables use in 3.3 V, 5 V, and dual-supply systems. It is also commonly used in test equipment and automated switching systems requiring low on-resistance channel selection.

Frequently Asked Questions

What bandwidth does the CD74HC4351EE4 support for analog signal switching?

The CD74HC4351EE4 provides a nominal bandwidth of 180 MHz, enabling it to route high-frequency analog signals with minimal attenuation, making it suitable for video, audio, and RF-adjacent multiplexing applications.

Can the CD74HC4351EE4 operate from a dual supply, and what voltage range is supported?

Yes, the CD74HC4351EE4 can operate from a dual supply with VCC-VEE range of 2 V to 10 V, and also works from a single supply of 2 V to 6 V, offering flexibility across different analog front-end designs.

How many analog channels does the CD74HC4351EE4 switch, and what package is used?

The CD74HC4351EE4 provides 8 analog channels in a 20-pin DIP package, allowing selection of one of 8 single-ended inputs or outputs through a 3-bit binary address, suitable for through-hole prototyping boards.

In what applications is the CD74HC4351EE4 preferred over a lower-channel-count multiplexer?

The CD74HC4351EE4 is preferred in data acquisition systems requiring 8 sensor inputs sharing a single ADC, reducing component count compared to using multiple 4-channel or 2-channel multiplexers with separate address decoding logic.
