SN74ABT7819A-15PN

Logic FIFOs Memory plays an important role in everyday electronics and instrumentation, providing high speed and flexibility. As one of the most popular memories, the SN74ABT7819A-15PN is an FIFO memory that supports data signal transmission between multiple hosts and systems. This article will discuss the application field and working principle of SN74ABT7819A-15PN.

Application field

The SN74ABT7819A-15PN is ideal for many application fields, particularly those requiring high data throughput. Applications include:

• Communication: Network communications, point-to-multipoint communication and instrument control.
• Medical equipment: Endoscopy, ultrasound imaging systems.
• Industrial automation systems: Robotics, printing, HVAC and chemical/pharmaceutical systems.
• Avionics: Air traffic control, missile guidance systems and satellite tracking.

Working Principle

The SN74ABT7819A-15PN is a Leading Edge FIFO, integrating First-In First-Out memory and 25-bit address width capability. The maximum data width supported by the FIFO is 8 bits, with a frequency of 100 MHz. The internal FIFO memory consists of 4K x 8 memory cells, clocked and controlled by the address pins. The device also includes an 8-bit data configuration terminal, which allows the user to select various data input and output configurations.

The SN74ABT7819A-15PN works by transferring data from the data bus to its internal memory. When the data bus is enabled, data is transmitted from the bus and stored in the internal memory of the FIFO. When the write pin goes high, the data previously stored in the internal memory will be transmitted to the output port. This process is repeated for both input and output data, and the address pins determine the starting address for both write and read operations.

The FIFO also features Error Reporting capability. This feature allows the user to determine if the data stored or transferred was correct or not. In case of an error, the Status LED indicates the presence of an error and alerts the user to take corrective action.

The SN74ABT7819A-15PN is a versatile FIFO memory that is well suited for applications requiring data transfer and storage at high speeds. It provides excellent performance, and its error reporting capability makes it especially useful in mission critical applications.
