ON Semiconductor MC74HC4066AN Quad Analog Switch/ Multiplexer/Demultiplexer IC

The MC74HC4066AN from ON Semiconductor is a versatile and high-performance quadruple analog switch IC, designed to function as a multiplexer/demultiplexer in a wide array of electronic applications. This integrated circuit is fabricated with silicon gate CMOS technology, ensuring low power consumption while maintaining high-speed operation comparable to LSTTL. It is a perfect choice for analog and digital multiplexing/demultiplexing, signal gating, and chopper applications.

The MC74HC4066AN features four independent switches capable of conducting signals from analog inputs to outputs. Each switch is a bilateral, single-pole, single-throw (SPST) device, which can be controlled by a digital control signal applied to its corresponding control input pin. The low "on" resistance of the switch ensures minimal signal distortion, making it an excellent choice for audio, video, and telecommunication signal routing.

With its wide operating voltage range of 2V to 6V, the MC74HC4066AN is highly flexible and can be used in various systems without the need for level-shifting circuits. This makes it suitable for interfacing with both TTL and CMOS logic families. Additionally, the IC has a low "off" leakage current, further enhancing its performance in applications where high impedance is critical.

The MC74HC4066AN comes in a 14-pin PDIP package, making it easy to integrate into through-hole printed circuit board designs. Its robust design ensures that it can withstand the rigors of commercial and industrial environments, with a wide operating temperature range of -55°C to 125°C.

Key features of the MC74HC4066AN include:

• Quad bilateral switch operation
• Low "on" resistance: 70 Ohm typical at Vcc = 4.5V, Ioh = 4.5mA
• Wide operating voltage range: 2V to 6V
• High noise immunity characteristic of CMOS devices
• Minimal propagation delay
• Compatible with TTL and CMOS logic levels
• 14-pin PDIP package for easy PCB integration
• Extended temperature range: -55°C to 125°C

Overall, the ON Semiconductor MC74HC4066AN is an excellent choice for designers looking to add flexible and reliable analog switching capabilities to their electronic projects or commercial products.
