- By toggling the clock input of a 74xx74 (or any flip-flop, really) and feeding the complementary output back into the data input, Jeri can get an output that is a 50% duty cycle feeding into the input of the chip.
- edge-triggered flip-flop
- flip-flops and latches
- triggered flip-flops
And each of our two ICS contains two of these flip flops, along with the ability to clear or reset them.

Examples
-
As with any electronic shortcut, there are a few drawbacks: the clock cycle feeding into the flip-flop has to be pretty fast; at least a few dozen kilohertz if you're sampling audio.

The initial design normally contains one or more system clocks driving a large number of flip-flops and latches.

So we're replacing this wire that goes from the output of the last flip flop around to all of these XOR gates.
-
Sampling the constant output from the flip-flop gives you a pulse train, and changing the width of the pulse is equivalent to changing the frequency of the pulse train.

When sampling an async input with a flip-flop, you always run the risk of violating setup or hold, which just means you might get a delay of one cycle or the tiny risk you hit metastability, which will generally resolve very fast in modern logic.

Because of the prevalence of edge-triggered designs in the industry, and until recently the absence of LSSD in the external market, a solution was needed that would allow a customer to design using edge-triggered flip-flops, yet produce an LSSD-compatible netlist.

The library includes a variety of sequential elements that offer functionality familiar to customers with logic design experience based on non-scan edge-triggered flip-flops; these elements also support IBM's full-scan design-for-test methodology.

Etymology
Flip-flop in electronics is named for how the circuit flips to one state and flops to the other, like a tiny switch that stays in one of two positions. So a flip-flop is used to store a single bit by switching between two stable states.
