The S-R Latch (Quickstart Tutorial) - Build Electronic Circuits
Before starting with the S-R latch you need to know what a latch is. A latch is an asynchronous circuit (it doesn’t require a clock signal to work), and it has two stable states, HIGH (“1”) and LOW (“0”), that can be used for storing binary data. Many sequential circuits and larger storage devices, such as shift … See more
