RS – Reset-set flip-flop circuit

Block SymbolLicensing group: STANDARD

Function Description
The RS block is a flip-flop circuit, which sets its output permanently to on as soon as the input signal S is equal to on. The other input signal R1 resets the Q output to off even if the S input is on. The NQ output is simply the negation of the signal Q.

The block function is evident from the inner block structure depicted below.

Inputs

S	Flip-flop set, sets the Q output to on	Bool
R1	Priority flip-flop reset, sets the Q output to off, overpowers the S input	Bool

Outputs

Q	Flip-flop circuit state	Bool
NQ	Boolean complementation of Q	Bool
