Working Principles

The 74ABT273CMSA operates based on the principles of clock-triggered flip-flops. When a clock signal is received at the CP pin, the data (D) input is transferred to the output pins (Q0-Q7). The stored data remains unchanged until the next clock signal arrives. The MR pin can be used to reset the flip-flop, clearing the stored data to a known state. The OE pin controls the visibility of the stored data at the outputs.
