SR – Set-reset flip-flop circuit

Block SymbolLicensing group: STANDARD

Function Description
The SR block is a flip-flop circuit, which sets its output permanently to on as soon as the input signal S1 is on. The other input signal R resets the Q output to off, but only if the S1 input is off. The NQ output is simply the negation of the signal Q.

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

This block propagates the signal quality. More information can be found in the 1.4 section.

Input

S1	Priority flip-flop set	Bool
R	Flip-flop reset	Bool
