SN74V273-7PZA

The SN74V273-7PZA belongs to the family of Logic – FIFOs Memory. It is an 8-bit High-performance First-in, Last-out (FIFO) buffer storage device which can store as much as 256 bytes of data in 8-bit increments. It integrates two vertical packet registers and a horizontal shift register on a single monolithic integrated circuit (IC).

The two ports of the SN74V273-7PZA are data input and output between the register sets. This FIFO is usually used in applications when the time required for one set of data to be received and stored is longer than the time for the other set of data to be transmitted and stored. Features of this FIFO include write-protection circuitry to prevent data corruption when full and empty flags for determining the current status of the storing process.

This FIFO IC is mainly used in various digital communication systems where multiple devices need to communicate with each other. The device is also found in general-purpose applications such as data and memory buffering, serial data and memory expansion, data input/output synchronizing, A/D conversion and display driving.

The working principle of the SN74V273-7PZA mainly depends on the data line flow. During the process of writing some data, data inputs must be sent through the input port and stored in the register sets by transferring them to the rightward. Reading of data is also done through the output port by transferring the data to the leftward. In addition, the device can be used in pair with two directions to transfer data between two parts simultaneously.

All operations related to writing and reading are done through the control pins of the device. For example, the Write Data (WRD) pin can be used to write new data to the FIFO device, while the Read Data (RDD) pin can be used to read stored data from the device. As well, the signal from the Load Address (LDA) pin is used to control the logic of data input registers, and the signal from the Read Address (RA) pin is used to control the logic of data output registers.

The SN74V273-7PZA is an ideal choice for systems that require a fast, efficient, and reliable buffering solution. It is a cost-effective and robust device that is reliable and easy to use. With the use of this device, data can be stored and retrieved quickly and with utmost accuracy.
