The first electronic latch was invented in 1918 by the British physicists William Eccles and F. W. Jordan. It was initially … See more

Transparent or asynchronous latches can be built around a single pair of cross-coupled inverting elements: vacuum tubes, bipolar transistors, field-effect transistors, inverters, and inverting logic gates have all been used … See more

Flip-flops and latches can be divided into common types: SR ("set-reset"), D ("data"), T ("toggle"), and JK (see History section above). The behavior of a particular type can be described by the characteristic equation th… See more

The input must be held steady in a period around the rising edge of the clock known as the aperture. Imagine taking a picture of a frog on a lily-pad. Suppose the frog then jumps into the water. If you take a picture of the frog as … See more

Flip-flops can be generalized in at least two ways: by making them 1-of-N instead of 1-of-2, and by adapting them to logic with more than two states. In the special cases of 1-of-3 encoding, or multi-valued ternary logic, … See more
