ADM208AN

The ADM208AN is an RS-232 interface driver and receiver that offers a bit-level shift and multiplexer function. It is used in a wide range of applications, such as communication between computers, data collection and automation control, in order to provide communication between two or more serial port devices. This device is also used to link low--voltage circuit boards with higher-voltage systems.

Application Field

ADM208AN is suitable for automotive, industrial, and telecom applications. It is also used for serial communication in computers, modems, terminals, PPCs, and other communication systems with RS-232 input/output interfaces. ADM208AN is usually used in applications where it is necessary to transfer data in a reliable and fast manner.

Working Principle

The ADM208AN is a dual-channel, low-power RS-232 interface driver and receiver. It operates at 3.0 V and 5.0 V supply voltages at a maximum data rate of 250 kpbs. The device is package in an 8 pin SSOP (small-outline integrated circuit) and is available in extended temperature range of -40 to +85 °C, making it suitable for extended temperature range applications. The data transmitted and received by the device is between two interface devices. To ensure that the data transmitted is error-free, the device includes various error detection and correction methods. It includes support for five different data transmission modes – single data, double data, even parity, and odd parity.

The ADM208AN also includes an internal multiplexer function, which allows it to multiplex data from one data output port to two outputs. This functionality is achieved by utilizing an internal tri-state buffer. The device also features an interference-free transmission line interface, which ensures that data received from an external source is transmitted accurately to the designated destination.

The ADM208AN has several features which make it suitable for a wide range of applications. These features include a wake-up function which allows the device to auto-sense the active state, reduced voltage operation which allows it to operate at -40 to +85 °C, and low power consumption which helps extend the life of the system.

Conclusion

The ADM208AN is a versatile RS-232 interface driver and receiver which offers a bit-level shift and multiplexer function. Its wide temperature operating range and low power consumption makes it suitable for a multitude of applications. It is an ideal choice for applications requiring reliable and fast serial data transmission.
