1
Q
what are the stables states of bistables (flip-flop)?
A
logic 0 or logic 1
2
Q
what must happen to the device if it has been set in one of its stable states?
A
must be completely reset to permanently change it to the opposite state
3
Q
in what condition would a bistable be removed from its latched condition?
A
when a signal is applied, or when supply is disconnected
4
Q

A
R-S bistable
5
Q
what inputs and outputs do R-S bistables have?
A
2 inputs, set and reset
2 outputs, q and q
6
Q
what happens when logic 1 is applied to set?
A
Q output will become or remain at logic 1
7
Q
what happens when logic 1 is applied to reset?
A
Q output to become or remain at logic 0
