This book taught me that a flip-flop is sometimes called a latch ;). Not just for babies apparently

- fwip 3y agoPedantic: A flipflop and a latch are different, but similar. Latches are set high or low whenever the corresponding input is pressed. Flipflops are edge-triggered, and in most setups only change at a clock cycle. One way to construct a flipflop is by wiring several latches together - see figure 11 of this pdf: https://www.cs.ucr.edu/~ehwang/courses/cs120b/flipflops.pdf https://www.cs.ucr.edu/~ehwang/courses/cs120b/flipflops.pdf
- dmwilcox 3y agoI had a niggling feeling they were different (realized after I posted) and I would get some reading. I haven't taken an EE course in a long time and miss it. Thank you!
- dmoy 3y agothey're not the same though? I've been out of EE for like 15 years so I forget exactly how, but I don't think they're the same. edit: yup sibling comment has it, that was what I was forgetting
- Deprecate9151 3y agoAnd reading up after this comment led to me learning some people make a distinction that latches are level triggered and flip-flops are edge triggered. I think I remember my digital logic professor using both. I don't recall there ever being a clear cut distinction like edge vs level set being made though. I wish I still had my notes.
