The MC3031 implements a RS NAND latch with an inversed result for when both inputs are the same. Only the Q output is available. When the S (inverse "set") input exclusively goes high, the output (Q) goes high and stays high even if S goes low again. When the R (inverse "reset") input exclusively goes high, the output (Q) goes low and stays low even if R goes low again. If both go high at the same time, the output goes high. If both go low at the same time, the output does not change.

See [[../MC3033/]] for a regular RS NAND latch.
