Introduction

The HCF4053M013TR is an integrated circuit from the HCF4053 family, produced by STMicroelectronics. It is part of the interface section of the chip and contains analog switches, multiplexers, and demultiplexers, which are integrated on the device functioning as signal routing components. In this article, we will have an overview of the application field and working principle of the HCF4053M013TR.

Overview

The HCF4053M013TR is a CMOS chip suitable for portable applications and other applications that require low-power signals. The device is specified for operation from 0°C to 70°C, with an absolute maximum rating of 85°C.

Features

• Low power consumption: 60 µA
• Supply voltage range: 2.0V–6.0V
• On resistance: 75 Ω max.
• Analog signal bandwidth: 6MHz max.
• Three digital control inputs: c0, c1, c2

The HCF4053M013TR has three independent single-pole-double-throw switches, a triple 2:1 multiplexer, a triple 1:2 demultiplexer, and an output enable control input. Each analog switch can block DC or AC signals, while the multiplexer and demultiplexer can be used to select and route signals. The output enable control input is provided so that all of the switches can be turned off when not in use.

Applications

The HCF4053M013TR is used in a number of applications, such as switching, multiplexing and demultiplexing of analog signals. It is also suitable for portable or battery-powered applications. The device has been found to be effective in audio signal routing, in medical equipment, amplifiers, voltage regulators, and consumer electronics.

Working Principle

The HCF4053M013TR is controlled by logic inputs c0, c1 and c2. These logic inputs select one of the analog switches, one of the multiplexers, and one of the demultiplexers, respectively. Each analog switch has a common terminal and two output terminals, while each multiplexer channel has an active low enable pin, an active low input pin, an active high output pin, and an active high inverted pin.

When one of the analog switches is selected, the common terminal is connected to one of the two output terminals, depending on the logic state of the control input c0. Similarly, when one of the multiplexers is selected, the logic input c1 determines which of the two input pins is connected to the output pin. The demultiplexer works in the same way, but with the logic state of c2 instead. When the output enable control input is active low, all of the switches are turned off, thus blocking the signals from being routed.

Conclusion

The HCF4053M013TR is a versatile integrated circuit which can be used for switching, multiplexing and demultiplexing of analog signals. Its low power consumption, wide supply voltage range and high speed switching capabilities make it suitable for use in a variety of applications such as consumer electronics, amplifiers, voltage regulators and audio signal routing. The device is controlled by three digital control inputs, which allow the user to select and route signals by means of the analog switches, multiplexers and demultiplexers.
