Loadable Toggle Flip-Flop with Toggle and Clock Enable and Asynchronous Clear and Preset

When the asynchronous clear (CLR) input is High, all other inputs are ignored and the output (Q) is reset Low. When the asynchronous preset (PRE) input is High, all other inputs are ignored and Q is set High. The load input (L) loads the data on input D into the flip-flop on the Low-to-High clock transition, regardless of the state of the clock enable (CE). When the toggle enable input (T) and the clock enable input (CE) are High and CLR, PRE, and L are Low, output Q toggles, or changes state, during the Low-to-High clock (C) transition. Clock transitions are ignored when CE is Low. When both CLR and PRE are active, the flip-flop output is unpredictable.
