Logic - Specialty Logic: 74ABT899CSC application field and working principle

74ABT899CSC is a 9 to 8 bit Transceiver with “Tri-state” outputs logic family. It is a dual-zone logic serial-to-parallel factor. In order to reduce the design complexity, 74ABT899CSC is used to process the serial-input data. It can also be used as a parallel-input to serial-output processor. It comprises a pair of differential-input data rate converters with "tri-state" outputs.

Application Field of 74ABT899CSC

74ABT899CSC can be used for a wide range of digital data processing such as networking and communication solutions, automotive electronics, industrial electronics, medical imaging, and more. One of the advantages of this device is that it is capable of being used both as a serial-to-parallel and as a parallel-to-serial device. This makes it applicable for many different applications which require serial/parallel conversion.

74ABT899CSC is mainly used to convert input parallel data into serial data. This type of conversion is useful in applications that require data transmission through long distances without the need of a high-speed communication link. It can also be used in data communication systems and in situations where multiple parallel data sources need to be merged into one serial data source.

Working Principle of 74ABT899CSC

74ABT899CSC operates by a differential-input to differential-output logic family. It is comprised of two separate logic cells with the same layout that can be accessed through a parallel data interface. Each of the cells has a differential input common-mode voltage range of 0.2V to 1.8V and an adjustable output current range from 0.55mA to 2.8mA. The devices are also fully tri-stateable in order to meet the needs of various applications.

The devices are also designed with frequency shaping circuitry. This is used to reduce signal reflections caused by transmission line impedance mismatching and to improve signal integrity with very low speeds. This allows for better data transmission in long distance applications.

The operation of the 74ABT899CSC is based on a 9-bit parallel input interface and 8-bit serial output. Its working principle can be simply described as follows:

1. The 9-bit parallel data is latched into the device.
2. The 8-bit serial output data is then generated.
3. The data is then shifted out of the device through the output port.

The 74ABT899CSC is designed to be used in high-speed applications. The device can operate up to a frequency of 133MHz. The device also features ESD protection, which makes it suitable for use in harsh environment applications.
