Toggle/Loadable Flip-Flop with Toggle and Clock Enable and Synchronous Set and Reset
The synchronous set input (S), when High, overrides all other inputs and sets data output (Q) High. (Set has precedence over Reset.) When synchronous reset (R) is High and S is Low, clock enable input (CE) is overridden and output Q is reset Low. When load enable input (L) is High and S and R are Low, CE is overridden and data on data input (D) is loaded into the flip-flop during the Low-to-High clock transition. When the toggle enable input (T) and CE are High and S, R, and L are Low, output Q toggles, or changes state, during the Low-to- High clock transition. When CE is Low, clock transitions are ignored.
