The MC74HC4051AFELG from ON Semiconductor is an advanced high-speed CMOS analog multiplexer/demultiplexer integrated circuit. This versatile component is designed to handle both digital and analog signals, and it is characterized by low quiescent current and low power dissipation, making it an ideal choice for battery-operated devices and power-sensitive applications.

This device is fabricated using silicon gate CMOS technology which ensures that it has the high noise immunity and low power consumption of standard CMOS integrated circuits, along with the ability to drive 10 LS-TTL loads. The MC74HC4051AFELG has an extensive operating voltage range from 2V to 6V, providing ample flexibility for varying power supply requirements.

The multiplexer/demultiplexer features a triple-diode protection on all control inputs, which can tolerate ±0.5V at VCC = 4.5V. It can handle input and output analog voltages that extend to the supply voltage levels, exemplifying its wide dynamic range. The device also exhibits low "on" resistance, typically around 70Ω at VCC = 4.5V.

With its single 8-channel multiplexing capability, the device can be used in a variety of applications such as signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems. Additionally, it is TTL compatible, making it easy to interface with traditional TTL logic families.

Encased in a Pb-free, RoHS-compliant SOEIAJ-16 package, the MC74HC4051AFELG ensures environmental responsibility without compromising on performance. Its package is also designed for optimal PCB space utilization, with a compact footprint that is ideal for densely packed boards.

ON Semiconductor's commitment to quality and reliability is evident in the MC74HC4051AFELG, making it a reliable choice for designers looking to incorporate a robust analog multiplexer/demultiplexer into their electronic systems.
