Functional Features

• Data storage: The 74ABT273CMTC can store data on its inputs (D0-D7) and retain it until a clock signal is received.
• Clock-triggered operation: The stored data is transferred to the outputs (Q0-Q7) based on the rising edge of the clock signal.
• Master reset: The IC includes a master reset input (MR), which allows all outputs to be cleared simultaneously when activated.
• Output enable: The output enable input (OE) controls whether the stored data is visible at the outputs or not.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low power consumption contributes to energy efficiency. - Wide operating voltage range allows for versatile applications. - Noise immunity ensures reliable data storage in noisy environments.

Disadvantages: - Limited storage capacity: The 74ABT273CMTC can only store a single bit of information. - Requires an external clock signal for proper operation.

Working Principles

The 74ABT273CMTC operates based on the principles of sequential logic. When the clock signal rises, the data present at the inputs (D0-D7) is transferred to the corresponding outputs (Q0-Q7). The stored data remains unchanged until the next clock signal arrives. The master reset input (MR) can be used to clear all outputs simultaneously, while the output enable input (OE) controls the visibility of the stored data at the outputs.
