flip-flop; bistable circuit
A digital electronic circuit that can store one bit of data, toggling between two stable states. Used in registers, counters, and memory elements.
A flip-flop can hold one bit of information.
This circuit uses a D-type flip-flop.
You can build a flip-flop out of two NAND gates.
The flip-flop's state changes on the rising edge of the clock.
