Working Principles

The SN74HCT273PWRG4 operates based on the principles of sequential logic. It stores and transfers data using flip-flops, which are controlled by a clock signal. When the clock signal transitions from low to high, the input data is latched and stored in the flip-flops. The stored data can then be retrieved from the output pins.

The asynchronous clear input allows for resetting all flip-flops to a known state when necessary. This feature ensures reliable operation during system initialization or error recovery.
