Functional Features

• The 74ABT374APW,112 is capable of storing and transferring data using its eight D-type flip-flops.
• It has a transparent latch that allows the input data to be latched onto the outputs when the latch enable (LE) signal is high.
• The output enable (OE) signal can be used to disable the outputs, preventing any changes in the stored data.
• The IC operates at high speed and consumes low power, making it suitable for applications requiring fast data transfer with minimal energy consumption.

Advantages and Disadvantages

Advantages: - High-speed operation enables quick data processing. - Low-power consumption helps conserve energy. - Octal design allows for efficient handling of multiple data inputs and outputs. - Transparent latch feature provides flexibility in data storage and transfer.

Disadvantages: - Limited voltage range (4.5V to 5.5V) may restrict compatibility with certain systems. - Propagation delay of 3.8ns (typical) may introduce slight delays in time-critical applications.

Working Principles

The 74ABT374APW,112 operates based on the principles of flip-flops and latches. When the latch enable (LE) signal is high, the input data is transferred to the outputs.
