LATCHES AND FLIP/FLOPS – Notes 1 Latches    are digital storage devices that use flip/flops to remember or latch  onto information. Logic circuits can be divided into 2 groups: combinatorial and sequential Combinatorial  produces more sophisticated circuits that perform  complicated functions and do arithmetic.  connect in one direction.  no loops  one output state for each possible state of input.  changing input, changes output, instantaneously.

Unformatted text preview: Sequential used to preserve previous output state. can depend on present input and past input. can be used to store information. basic building block is a flip/flop. several gates feed output back into input.
