In the previous installment, we talked about why flip flops are such an important part of digital design. We also looked at some latch circuits. This time, I want to look at some actual flip flops&… ...

S3 switches on when the latch is off. (Q is high.) C4 to C6 are optional for improving transient-simulation convergence. Figure 3a shows one possible test circuit for the 555 macromodel. This example ...

Measured waveforms from the latch circuit during an output overvoltage event demonstrate how the circuit operates . The power-supply output voltage is configured for a nominal 35 V.

CircuitLab is coming up on its one year anniversary, and the startup (now part of Y Combinator's winter 2013 cohort) now boasts 70,000 monthly active users, who run an average of one circuit ...

The Falstad simulator has an example circuit of a NAND SR latch you can pick from the example circuits menu. The Verilog equivalent is simple (use nor, if you prefer): ...
