While the 74HC574 is famous for its 3-state outputs used on shared data buses, the 74HC273 takes a different approach. \u003cspan class=\"citation-153 citation-end-153\"\u003eThis 20-pin integrated circuit contains eight D-type flip-flops that share a common clock, but instead of an output enable pin, it features a master asynchronous Reset pin.\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eEvery time the clock signal transitions from Low to High, all eight input pins are instantly read and locked into memory on the eight output pins. The true power of the 74HC273 lies in its Master Reset (Clear) pin. Pulling this active-Low pin to Ground instantly wipes all eight outputs back to zero, completely ignoring the clock and data inputs. Because the outputs are standard push-pull logic rather than tri-state, they are always active, making this chip ideal for directly driving LEDs, displays, or downstream logic gates where you need a guaranteed zero state on startup.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eKey Features \u0026amp; Functional
