Webshown in Figure 4(a). This circuit is called a SR latch. In addition to the two outputs Q and Q', there are two inputs S' and R' for set and reset respectively. Following the convention, the prime in S and R denotes that these inputs are active low. The SR latch can be in one of two states: a set state when Q = 1, or a reset state when Q = 0. WebThe additional AND gates detect when the counting sequence reaches “1001”, (Binary 10) and causes flip-flop FF3 to toggle on the next clock pulse. Flip-flop FF0 toggles on every clock pulse. Thus, the count is reset and starts over again at “0000” producing a synchronous decade counter. We could quite easily re-arrange the additional AND gates …

In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will output its state (often along with its logical complement too). It is the basic storage … See more The first electronic latch was invented in 1918 by the British physicists William Eccles and F. W. Jordan. It was initially called the Eccles–Jordan trigger circuit and consisted of two active elements (vacuum tubes). … See more Timing parameters The input must be held steady in a period around the rising edge of the clock known as the aperture.
