SN74ACT373DWG4 Application Field and Working Principle

The SN74ACT373DWG4 is an octal D-type transparent latch, part of the TPB family of integrated circuits from Texas Instruments. It is categorized under the Logic - Latches family and is used to store the output of eight data lines, and has a combination of eight D-type inputs and eight D-type outputs. The D-type latches are triggered with the latch enable (LE) signals and the data information present at the D inputs will be forwarded to the output lines.

Functional Block Diagram and Pin Configuration

The SN74ACT373DWG4 consists of an octal transparent latch and is focused mainly at applications needing data/address storage. It has a total of twenty pins, classified as twelve input pins and eight output pins. The main inputs connected to the latch are the Data Latch Enable (DLE) pins and the data inputs (D0–D7). The outputs are the transparent latch outputs (Q0–Q7), VCC (6 pins) and Ground (2 pins).

The latch enable pin is used to enable the latch block by switching between high and low levels. When LE is high, data from the DIN lines is written to the transparent latch and available at the DOUT side. When it is low, data being addressed will be empty and the transparent latch output (Q0–Q7) will be empty.

Working Principle

The SN74ACT373DWG4 is a powerful latch used to read and store data from eight external input data sources. It consists of an octal latch, meaning that it can store up to eight separate inputs. It typically works as a kind of data/address buffer. The latch is triggered using the latch enable (LE) signal which tells the device when to store the data and when to read the stored data.

The operation works like this: When the latch enable (LE) signal is in its active high state, the data present at the data inputs (D0-D7) is copied on to the outputs (Q0-Q7). This means that the data inputs which are connected to the device are registered and stored in the SN74ACT373DWG4\'s memory bank. When the latch enable signal is in its inactive low state the data values stored in the device\'s memory bank remain unchanged, however no new data is written to the outputs unless the LE signal is again made active.

Real-World Applications

The SN74ACT373DWG4 is ideally suited for applications in logic address decoding, data/address storage, signal buffering, data transfer, etc. Due to its versatile design, it is used in a wide range of applications in varying industries, including computer technology, telecommunications, communications, automotive, and industrial. Examples of its use include bus scheduling and data routing, essential operations in computer memory management. It is also used in signal buffering and data transfer applications.

The SN74ACT373DWG4 has become a popular choice for logic environments due to its high speed operation and low power consumption. Speed is one of the device\'s most attractive features, being capable of handling data signals of up to 25MHz. It also operates at a low power consumption of up to 20mW, which makes it ideal for low power applications.

Conclusion

The SN74ACT373DWG4 is an attractive device due to its high speed capabilities and low power consumption. It provides a versatile solution for the storage and buffering of data in various industries. Thanks to its octal position design, this device can easily be used in data transfer applications in fields such as computers, communication, telecommunications, automotive, and industrial.
