SN74ACT7808-20FN is a FIFOs Memory device manufactured by Texas Instruments, whose basic technical parameters are 8-bit FIFO and 8-channel, 1.8V-3.6V wide operating voltage, and 5~20 MHz clock rate. The SN74ACT7808-20FN consists of two parts: a FIFO Memory and a control logic circuit, and the two parts are combined as an independently functional unit to provide an independent, transparent data storage.

The FIFO memory of SN74ACT7808-20FN is a data flow buffer which can store data temporarily. At both the read and write terminals, the FIFO Memory Module can freely enter and leave data, and can provide a data stream of data connected by the beginning and end of the data stream, so it can late carrying effect. The FIFO memory module used in this device is a standard 8-bit memory module, with a capacity of 8-bit words. It is provided with three single-ended write terminals (WE) and three single-ended read terminals (RE), as well as a single-ended full/empty flag (FE) bit.

The control logic circuit of SN74ACT7808-20FN is used to control the write and read operations of the FIFO memory. The read control logic is the same as the write control logic, except that instead of the write enable signal input, it uses the read enable signal input to control the FIFO operation. The full/empty control logic works in the following way: when the data storage space of the FIFO Memory is full, the full/empty control logic outputs a signal indicating that the FIFO Memory is full; when the data storage space of the FIFO Memory is empty, the full/empty control logic outputs a signal indicating that the FIFO Memory is empty.

The SN74ACT7808-20FN has many excellent features and wide application fields. It can be used for data buffering and processing in communication systems, computer systems, multimedia systems and other kind of circuits. Its excellent features provides various benefits to other system, such as:

• It saves power consumption, because the FIFO Memory can store a large amount of data, and reduce the need for the system to continuously access memory resources.
• It can reduce the burden of system bus bandwidth, because FIFO buffer can store temporarily data, and release the bus pressure.
• It can reduce logical complexity in system, because the FIFO Memory can be used to sort and process data according to certain methods, and reduce the need of the system to process data repetitively.
• It can prevent data errors, because the FIFO Memory can reliably store data that are continuously transmitted and received in a data stream.

In conclusion, the SN74ACT7808-20FN is a versatile and integrated FIFOs Memory device with wide application fields. It has excellent features which enable it to provide various benefits to other systems. Its FIFO Memory and Control Logic Circuit enable it to perform buffering, sorting and processing data with high reliability and power efficiency, which make it an excellent device for use in communication, computer, and multimedia systems.
