PRESET and CLEAR inputs are normally synchronous.

More Questions from Flip-Flops

• Edge-triggered flip-flops can be identified by the triangle on the clock input.
• A J-K flip-flop and associated waveforms are shown below. The circuit is operating properly.
• A D-type latch is able to change states and "follow" the D input regardless of the level of the ENABLE input.
• A negative edge-triggered flip-flop will accept inputs only when the clock is LOW.
• Latches are tristate devices whose state normally depends on asynchronous inputs.
• The term CLEAR always means that .
• Parallel data transfers between two different sets of registers require more than one shift pulse.
• The J-K flip-flop is a standard building block of clocked (sequential) logic circuits known as logic standard primitives.
• A D flip-flop is constructed by connecting an inverter between the SET and clock terminals.
• A flip-flop is in the CLEAR condition when .
