Overview

The CD74HC4051E is a high-speed silicon-gate CMOS analog multiplexer/demultiplexer that acts as an 8-channel electronic switch. It can handle both digital and analog signals with a voltage range of up to 6V in single-supply or +/-5V in dual-supply configurations. This 16-PDIP component features break-before-make switching and is logic-level compatible with LSTTL devices.

Why Choose This Part

The part offers a high bandwidth of 180MHz and low leakage current of 400nA, making it suitable for precision signal paths. Its through-hole 16-PDIP package is ideal for prototyping, and the wide operating temperature range ensures reliability in harsh environments.

Applications

Analog Signal Multiplexing
Routing multiple sensor inputs to a single ADC pin on a microcontroller to expand input capacity.
Digital Signal Gating
Switching high-speed digital logic signals with minimal propagation delay in programmable logic circuits.
Factory Automation
Managing signal paths for industrial instrumentation and control systems within a -55C to 125C temperature range.
Audio Signal Routing
Switching low-level audio signals in consumer electronics and televisions using its 180MHz bandwidth.

Getting Started

For rapid prototyping, plug the 16-PDIP package directly into a standard breadboard or a 0.1-inch pitch socket. Connect the select pins (A, B, C) to microcontroller GPIOs and ensure the Enable (E) pin is pulled low to activate the switch. When switching analog signals, utilize the Vee pin for negative rail supplies if bipolar signals are required.
