Gli altri nomi sono stati coniati da Phister. Essi differiscono leggermente da alcune delle definizioni date di seguito. Lindley spiega che ha sentito la storia del flip-flop JK da Eldred Nelson, che è responsabile per l'invenzione del termine mentre lavorava alla Hughes Aircraft. I flip-flop in uso alla Hughes al tempo erano tutti del tipo che sarebbe stato conosciuto come J-K. Nel progettare un sistema logico Nelson assegnava lettere agli ingressi dei flip-flop nel modo seguente: #1: A & B, #2: C & D, #3: E & F, #4: G & H, #5: J & K. Nelson ha usato le notazioni "j-input" e "k-input" in una richiesta di brevetto presentata nel 1953.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Flip-flop_SR">Flip-flop SR</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Flip-flop&veaction=edit&section=2" title="Modifica la sezione Flip-flop SR" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Flip-flop&action=edit&section=2" title="Edit section's source code: Flip-flop SR"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:SR_(Clocked)_Flip-flop.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/48/SR_%28Clocked%29_Flip-flop.svg/220px-SR_%28Clocked%29_Flip-flop.svg.png" decoding="async" width="220" height="220" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/48/SR_%28Clocked%29_Flip-flop.svg/330px-SR_%28Clocked%29_Flip-flop.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/48/SR_%28Clocked%29_Flip-flop.svg/440px-SR_%28Clocked%29_Flip-flop.svg.png 2x" data-file-width="100" data-file-height="100" /></a><figcaption>Simbolo circuitale <a href="/wiki/ISO" class="mw-redirect" title="ISO">ISO</a> del flip-flop SR.
