Overview

The MC74HC4051ADR2G is a high-performance 8-channel analog multiplexer/demultiplexer utilizing silicon-gate CMOS technology. It is designed to route both digital and analog signals with a voltage range up to 6V, providing a single-circuit 8:1 switching configuration in a compact 16-SOIC package. This component features low crosstalk and improved linearity compared to older metal-gate counterparts.

Why Choose This Part

This device offers a high 80MHz bandwidth and low leakage current of 200nA, making it suitable for precision signal paths. Its wide operating temperature range from -55C to 125C ensures reliability in harsh environments, while the diode protection on all inputs and outputs guards against electrostatic discharge and signal overshoots.

Applications

Analog Signal Routing
Switching between eight different analog sensor inputs into a single ADC channel in industrial measurement systems.
Digital Data Multiplexing
Consolidating multiple digital status signals onto a single GPIO line for microcontrollers with limited pin counts.
Audio Signal Selection
Selecting between various low-level audio sources in consumer or professional audio equipment with minimal noise injection.
Function Generators
Routing different waveform outputs or gain stages in test and measurement instrumentation.

Getting Started

To integrate this device, provide a stable supply voltage between 2V and 6V and connect the three binary select inputs (A, B, C) to your microcontroller's GPIO. Ensure that the input signal voltages do not exceed the supply rails to prevent latch-up, and utilize the Enable pin to disconnect all channels when the bus must be high-impedance.
