A D latch has one data-input line.

More Questions from Flip-Flops

• The 7474 has two distinct types of inputs: synchronous and asynchronous.
• The gated S-R flip-flop is asynchronous.
• Using knowledge from previous chapters, an S-R flip-flop circuit is easy to design.
• A flip-flop's normal starting state when power is first applied to a circuit is always the SET state.
• Multivibrators must be level-triggered.
• Simple gate circuits, combinational logic, and transparent S-R flip-flops are synchronous.
• The 555 timer can be used in either the astable or monostable modes.
• The Q output of a flip-flop is normally HIGH when the device is in the "CLEAR" or "RESET" state.
• The S-R flip-flop has no invalid or unused state.
• A one-shot circuit is also known as a timer.
