When cascading flip-flops which share the same clock (as in a shift register), it is important to ensure that the t CO of a preceding flip-flop is longer than the hold time (t h) of the following flip-flop, so data present at the input of the succeeding flip-flop is properly "shifted in" following the active edge of the clock.
Flip-flop and latch are not the same; so, they deserve separate pages (as it is). Flip-flop and latch are closely related; so, the two pages have to be closely related as well. The latch precedes chronologically the flip-flop. Eccles and Jordan have invented a latch, not a flip-flop; so, the data about their patent have to be placed on Latch.
If the output of the flip-flop is low, and a high clock pulse is applied with the input being a low pulse, then there is no need for a state transition. The extra computation to sample the inputs cause an increase in setup time of the flip-flop; this is a disadvantage of this technique.
The output of a flip-flop is constant until a pulse is applied to its "clock" input, upon which the input of the flip-flop is latched into its output. In a synchronous logic circuit, an electronic oscillator called the clock generates a string (sequence) of pulses, the "clock signal".
It's the "flip" and "flopping" that sets up the instability in the flip flop. Such "flipping" and "flopping" doesn't exist with the latch. The solution is to stop calling latches flip flops (i.e., show the difference between asynchronous and synchronous inputs/outputs). —TedPavlic (talk/contrib/@) 21:16, 16 July 2009 (UTC)
An edge-triggered flip-flop can be created by arranging two gated latches in a master–slave configuration. It is so named because the master latch controls the slave latch's value and forces the slave latch to hold its value, as the slave latch always copies its new value from the master latch.
A multivibrator is an electronic circuit used to implement a variety of simple two-state [1] [2] [3] devices such as relaxation oscillators, timers, latches and flip-flops. The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I. It consisted of two vacuum tube ...
A 4-bit ring counter using D-type flip flops. A latch or a flip-flop is a circuit that has two stable states and can be used to store state information. They typically constructed using feedback that crosses over between two arms of the circuit, to provide the circuit with a state.
