DS14C89AN is a 2-wire type exchange switch, which can communicate with microcomputer (single chip) through serial communication, which is specially designed for single chip. It is an ‘interface device’, or an ‘interface’. It is a kind of electronic devices used to interconnect two electronic devices, two computer systems, two communication systems, two microprocessors, so that they can exchange information.

DS14C89AN is used in various applications, and its working principle can be divided into three parts.

Application Field

1. Automobile Electronics: DS14C89AN is used in many electronic products in the automotive industry, such as electronic control systems, automotive audio and video systems and automotive digital products, as well as some special applications, such as power switches and fuel injection control systems.

2. Communication Electronics: DS14C89AN is widely used in many fields of communication engineering. For example, communication protocol switching and transmission, GPS system, wireless communication, communication control systems and audio and video transmission control systems.

3. Consumer Electronics: DS14C89AN is widely used in many fields of consumer electronics, including aircraft navigational systems, medical equipment, intelligent home system, audio-visual product control systems and household appliances.

Working Principle

DS14C89AN is a micro-part that is designed to bridge between two electronic systems, two micro voltage regulators, or two communication systems. When power is provided to DS14C89AN, it receives commands in the form of digital signals and sends corresponding signals to the target device.

Firstly, the digital signal transmitted by microcomputer is received, and the chip will extract the serial data sent by the computer. Then these data will be analyzed and the chip will output appropriate serial data bus according to the serial commands.

Secondly, when it receives data from the target device, the chip will extract the serial data sent by the target device, convert it into a logic signal and output it through the DOUT port.

Finally, the chip will control the target device according to the logic signal it receives. For example, it can power on or power off a certain device.

In summary, the working principle of DS14C89AN is not complicated. It is an effective and reliable way to facilitate the communication between two devices. In addition, it has a long service life and can adapt to different environments.
