Functional Features

• Transparent Latching: The 74ABT373ADB,112 features transparent latching, allowing the inputs to be latched and stored when the latch enable (LE) signal is high.
• 3-State Outputs: The IC provides 3-state outputs, enabling the outputs to be in a high-impedance state when the output enable (OE) signal is low.
• High-Speed Operation: With its ABT (Advanced BiCMOS Technology), the IC offers high-speed operation suitable for applications requiring fast data transfer.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer. - Transparent latching allows for easy storage and transfer of data. - 3-state outputs provide flexibility in controlling the output signals.

Disadvantages: - Limited latch capacity (8 bits) may not be sufficient for certain applications requiring larger data storage.

Working Principles

The 74ABT373ADB,112 operates based on the principles of transparent latching. When the latch enable (LE) signal is high, the inputs (D0-D7) are latched and stored in the internal memory. The stored data can then be accessed through the corresponding outputs (Q0-Q7). The output enable (OE) signal controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74ABT373ADB,112 is commonly used in various electronic systems that require data storage and transfer. Some application field plans include:

1. Microprocessors and Microcontrollers: The IC can be used to store and transfer data between the processor and external devices, such as memory modules or input/output peripherals.
2. Communication Systems: It can be employed in communication systems for buffering and transferring data between different components, such as transceivers or data routers.
3. Data Acquisition Systems: The IC can be utilized in data acquisition systems to latch and store analog or digital signals for further processing or analysis.
