Flip-flop data pin driven by a constant value
WebMar 19, 2024 · Asynchronous inputs on a flip-flop have control over the outputs (Q and not-Q) regardless of clock input status. These inputs are called the preset (PRE) and clear … In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will output its state (often along with its logical complement too). It is the basic storage … See more The first electronic latch was invented in 1918 by the British physicists William Eccles and F. W. Jordan. It was initially called the Eccles–Jordan trigger circuit and consisted of two active elements (vacuum tubes). … See more Flip-flops and latches can be divided into common types: the SR ("set-reset"), D ("data" or "delay" ), T ("toggle"), and JK. The behavior of a … 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, such an element may be referred to as a flip … See more • FlipFlop Hierarchy Archived 2015-04-08 at the Wayback Machine, shows interactive flipflop circuits. • The J-K Flip-Flop • Shirriff, Ken (August 2024).
