This article will be discussing the application fields, working principles and characteristics of the 74ALVCH16501DL.

Application Field

The application field of the 74ALVCH16501DL mainly lies in the automobile field. It is used in vehicle embedded control systems such as the power systems, braking systems, and restraint systems that are needed in the vehicle automation. In the transportation and railway control systems, it serves as the input and output interfaces for the control systems. It is also the interface between remote control and autonomous control systems. Additionally, in industrial automation systems, the 74ALVCH16501DL serves as a connection between the automated production line and the control center.

Working Principle

The working principle of the 74ALVCH16501DL is to provide the Universal Serial Bus (USB) port with a priority encoder output. When there is an active buffer connected, the output will be a low level signal to indicate that the USB port is in its “busy” state. The circuit also functions to control the flow of data in the USB port by determining the priority of a signal or commands that is issued to the USB port. The circuit can be used to obtain the highest priority of a signal. The priority encoding signal will be further processed by the microcontroller and then transferred to the USB controller for signal transmission.

Characteristics

One of the characteristics of the 74ALVCH16501DL is the highly adjustable control. It has adjustable active buffer with a voltage adjustable range of 0.15V to 4.0V, which allows the circuit to operate at different voltage levels. Furthermore, it is also compatible with the Universal Serial Bus system. Additionally, the circuit has a high switching speed and can maintain a stable signal throughout its operation. Its high accuracy of signal data transmission also contributes to its reliability in handling multiple signals.

Conclusion

In conclusion, the 74ALVCH16501DL is a logic circuit specially designed for universal bus functions. It is mainly used for the application field of automobile, transportation, railway and industrial automation systems. Its working principle is based on providing the USB port a priority encoder output and adjustable active buffer. Its characteristics include an adjustable control range, compatible with Universal Serial Bus system, high switching speed and a reliable signal transmission.
