ON Semiconductor MC14052BD Analog Multiplexer/Demultiplexer

The MC14052BD from ON Semiconductor is a versatile and high-performance analog multiplexer/demultiplexer integrated circuit designed to handle a wide range of signal switching tasks. This device is part of the MC14052 series and provides an efficient solution for routing analog or digital signals in various electronic systems.

This particular model comes in a compact SOIC-16 package, making it suitable for space-constrained applications. The MC14052BD features dual 4-channel multiplexer/demultiplexer configurations, enabling it to switch one of four input signals to a common output or vice versa in each section. This flexibility makes it an ideal choice for use in data acquisition systems, communication systems, test equipment, and many other applications requiring a high degree of signal routing flexibility.

The MC14052BD operates over a broad voltage range from 3V to 18V, providing compatibility with most logic levels and allowing it to interface with both CMOS and TTL logic. The low ON resistance and high OFF resistance ensure minimal signal distortion and excellent isolation between channels, which is critical for maintaining signal integrity in complex electronic systems.

Key features of the MC14052BD include:

• Wide analog input voltage range: 3V to 18V
• Low ON resistance: 175Ω (Typ) over 15Vp-p signal input range
• High OFF resistance: Channel leakage of ±100pA at 18V
• Fast switching times: tON = 250ns and tOFF = 175ns at VDD - VEE = 10V
• Low quiescent current: 80nA (Typ)
• Matched switch characteristics: ΔRON = 5Ω (Typ)
• Bidirectional operation
• ESD protection: HBM > 2000V

The MC14052BD is designed to be used in a wide array of applications including signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems. Its robust design ensures reliable operation even in harsh environments, making it a trusted component in industrial, automotive, and consumer electronics.

With its combination of flexibility, performance, and ON Semiconductor's reputation for quality, the MC14052BD is an excellent choice for designers looking to add versatile signal routing capabilities to their electronic projects.
