Working Principles

The 74HC73D,653 operates based on the principles of JK flip-flops. It has two independent flip-flops, each with a J and K input, a clock pulse input, and separate set and reset inputs. The flip-flops store and manipulate binary information based on the input signals received.

When the clock pulse is triggered, the flip-flop captures the state of the J and K inputs and updates its output accordingly. The clear input can be used to reset the flip-flop to a known state. The complementary outputs provide both the inverted and non-inverted versions of the stored information.
