Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with a wide range of systems - High-speed operation enables efficient data transfer - Schmitt-trigger inputs provide robustness against noise - Compact TSSOP package saves board space

Disadvantages: - Limited output current may restrict use in certain applications - Lack of additional features compared to more advanced flip-flop types

Working Principles

The 74LVX74TTR is a positive-edge-triggered flip-flop, meaning that the stored data is transferred to the outputs only when a rising edge is detected on the clock input. The clear and preset inputs allow for initialization of the flip-flop's state. The complementary outputs provide both the inverted and non-inverted versions of the stored data.
