STMicroelectronics M74HC4052M1R Multiplexer/Demultiplexer IC

The M74HC4052M1R is a high-speed CMOS dual 4-channel analog multiplexer/demultiplexer with a common select logic, manufactured by STMicroelectronics. This integrated circuit (IC) is designed to provide efficient and reliable performance in a variety of digital and analog switching applications. With its advanced silicon-gate CMOS technology, it offers low power dissipation combined with high noise immunity and speed.

This versatile component features two separate four-channel multiplexer/demultiplexer sections, each with its own binary control inputs, A and B, and an inhibit input. The inhibit input is used to disable the multiplexer/demultiplexer, ensuring all channels are off. The common select logic includes two binary control inputs, S1 and S2, which determine the particular channel to be enabled. When a logical "1" is present at the inhibit input, all channels are off.

The M74HC4052M1R can handle both digital and analog signals, and it can process signals that can swing between VCC as a positive limit and VEE as a negative limit. This dual-range capability makes it exceptionally versatile in mixed-signal environments. The IC's analog inputs/outputs can swing between VCC and VEE, ensuring a broad range of signal handling.

Key features of the M74HC4052M1R include:

• Low power dissipation: ICC = 4µA (max) at TA = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Low "ON" resistance: 70Ω (typ) at VCC – VEE = 4.5V
• Wide operating voltage range: VCC (opr) = 2V to 6V
• Fast switching: tPD = 13ns (typ) at TA = 25°C, VCC = 4.5V
• ESD performance: HBM > 1KV; MM > 200V

The M74HC4052M1R is available in a variety of packages, including the compact SO-16, which is suitable for space-constrained applications. Its robust design ensures that this multiplexer/demultiplexer can be used in a wide range of applications, from signal routing in consumer electronics to data acquisition systems and communication infrastructure.

With its combination of flexibility, efficiency, and performance, the M74HC4052M1R from STMicroelectronics is an ideal choice for designers looking to implement a reliable multiplexing/demultiplexing solution in their digital or analog systems.
