Asynchronous flip- flop preset and clear inputs generally:
A) cause the outputs to change states depending on the SR, JK, or similar controlling inputs.
B) clear the inputs so the flip- flop can start over.
C) cause the outputs to change states as soon as the input clock makes the desired transition.
D) act as manual overrides that cause the outputs to change states regardless of the inputs or clock transitions.

Question

Quizplus · Accepted Answer

Preset and clear inputs on asynchronous flip-flops act as manual overrides, allowing the outputs to change state immediately, regardless of the clock transitions or other input states. These inputs are used to set the flip-flop to a known state quickly.
