Working Principles

The DM74ALS273SJ is a positive-edge triggered D-type flip-flop. It stores data on the rising edge of the clock signal (CLK) when enabled. The eight data inputs (D0-D7) are latched into the flip-flop on the rising edge of the clock, and the stored data can be retrieved from the eight outputs (Q0-Q7). The asynchronous clear input (CLR) resets the flip-flop to its initial state, clearing all stored data.

Detailed Application Field Plans

The DM74ALS273SJ is commonly used in digital systems where sequential logic is required. Some application fields include: 1. Microprocessors and microcontrollers 2. Data storage and retrieval systems 3. Communication systems 4. Control systems 5. Digital signal processing
