ON Semiconductor MC74HC4051FL1 Analog Multiplexer/Demultiplexer

The MC74HC4051FL1 is a versatile, high-performance analog multiplexer/demultiplexer integrated circuit brought to you by ON Semiconductor, a leading provider of semiconductor-based solutions. This device is a part of the HC4051 series and is fabricated using silicon gate CMOS technology which ensures that it has the high noise immunity and low power consumption characteristics of standard CMOS integrated circuits, along with the ability to drive 10 LSTTL loads.

With its single 8-channel configuration, the MC74HC4051FL1 is capable of handling both digital and analog signals, and it can process signals that can extend to the supply voltage levels. Its design allows for bidirectional operation and provides for virtually unlimited switching cycles, making it a reliable choice for a wide range of applications.

The multiplexer/demultiplexer function is controlled by three select inputs (S0, S1, S2), and an enable input (E). The enable input can be used to disable the device so that all channels are off, which is particularly useful in power-saving modes. When the device is enabled, one of the eight channels will be selected based on the binary value of the select inputs.

Key features of the MC74HC4051FL1 include:

• Low ON Resistance: 125 Ω (typical) at VCC = 6V
• Low Crosstalk between Switches: Ensuring minimal signal interference.
• Wide Operating Voltage Range: From 2V to 6V, compatible with a variety of logic families.
• Fast Switching and Propagation Speeds: For responsive performance in critical applications.
• Break-before-make Switching: Prevents momentary shorting when switching between channels.
• ESD Performance: HBM > 2000V, Machine Model > 200V, for robustness and reliability.

This device is ideal for a range of applications, including signal gating, multiplexing, analog-to-digital conversion, data routing, and many more where high-bandwidth and precision are required. The MC74HC4051FL1 is available in a flat package, making it suitable for surface mount technology and ideal for compact and high-density electronic assemblies.

ON Semiconductor's commitment to quality and environmental standards is evident in the MC74HC4051FL1, ensuring that it meets the requirements for a variety of commercial and industrial markets. With its combination of features, the MC74HC4051FL1 is a practical choice for designers looking for a reliable and efficient solution for their multiplexing and demultiplexing needs.
