Overview

The CD74HC4051M96 is a high-speed CMOS 8-channel analog multiplexer/demultiplexer designed for both digital and analog signal switching. It utilizes silicon-gate CMOS technology to achieve operating speeds similar to LSTTL while maintaining the low power consumption of standard CMOS integrated circuits. This device can handle analog signal levels up to 6V peak-to-peak and features an enable input to disconnect all channels.

Why Choose This Part

This device offers a wide operating temperature range of -55C to 125C and a high -3dB bandwidth of 180MHz, making it suitable for high-frequency signal switching. It supports flexible power configurations, including single-supply operation from 2V to 6V or dual-supply operation from +/-1V to +/-5V. The 130-ohm maximum on-state resistance ensures relatively low signal distortion across the full supply range.

Applications

Analog Signal Multiplexing
Routing multiple sensor inputs to a single ADC pin on a microcontroller to expand input capacity.
Digital Signal Routing
Switching high-speed digital signals between different communication paths or peripherals.
Signal Gating
Using the inhibit pin to quickly enable or disable a signal path in precision measurement circuits.
Programmable Gain Amplifiers
Selecting different resistor values in an op-amp feedback loop to adjust gain stages dynamically.

Getting Started

To evaluate this part, connect the select pins (S0-S2) to digital logic to control the 8-to-1 routing. Ensure the VEE pin is connected to ground for single-supply operation or to a negative rail for dual-supply analog signals. Decouple the VCC pin with a 0.1uF ceramic capacitor close to the 16-SOIC package to minimize switching noise.
