H = HIGH Level L = LOW Level Q0 = The Level of Q before the indicated input conditions were established.
Note 1: For latches with double S inputs:
H = both S inputs HIGH
L = one or both S inputs LOW
Note 2: This output level is pseudo stable; that is, it may not persist when the S and R inputs return to their inactive (HIGH) level.
