A latch can act as a contact-bounce eliminator.

More Questions from Flip-Flops

• A one-shot is a special type of multivibrator that must be triggered to produce each output pulse.
• When using edge-triggered flip-flops, the data is entered into the flip-flop on the leading edge of the clock, but the output does not change until the trailing edge of the clock.
• In VHDL, each instance of a component is given a name followed by a semicolon and the name of the library primitive.
• PRESET and CLEAR inputs are normally synchronous.
• 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 .
