Working Principles

The DM74ALS273MSA is a positive-edge-triggered flip-flop that can store and transfer data based on the rising edge of the clock signal. When the clock is high, the data inputs (D0-D7) are latched and stored in their respective flip-flops. The stored data can then be accessed from the output pins (Q0-Q7). The clear input (CLR) can be used to reset all flip-flops to a low state when activated.
