R S Q
An extension of the RS ip- op includes an additional enable input that is gated into each of the other two inputs Figure 144 depicts an RS ip- op consisting of two NOR gates In addition, an enable input is connected through two AND gates to the RS ip- op, so that an input to the R or S line will be effective only when the enable input is 1 Thus, any transitions will be controlled by the enable input, which acts as a synchronizing signal The enable signal may consist of a clock, in which case the ip- op is said to be clocked and its operation is said to be synchronous The same circuit of Figure 144 can be used to illustrate two additional features of ip- ops: the preset and clear functions, denoted by the inputs P and C, respectively When P and C are 0, they do not affect the operation of the ip- op Setting P = 1 corresponds to setting S = 1, and therefore causes the ip- op to go into the 1 state Thus, the term preset: this function allows the user to preset the ip- op to 1 at any time When C is 1, the ip- op is reset, or cleared (ie, Q is made equal to 0) Note that these direct inputs are, in general,

asynchronous; therefore, they allow the user to preset or clear the ip- op at any time A set of timing waveforms illustrating the function of the enable, preset, and clear inputs is also shown in Figure 144 Note how transitions occur only when the enable input goes high (unless the preset or clear inputs are used to override the RS inputs) Another extension of the RS ip- op, called the data latch, or delay element, is shown in Figure 145 In this circuit, the R input is always equal to the inverted S input, so that whenever the enable input is high, the ip- op is set This device has the dual advantage of avoiding the potential con ict that might arise if both R and S were high and reducing the number of input connections by eliminating the reset input This circuit is called a data latch or delay because once the enable input goes low, the ip- op is latched to the previous value of the input Thus, this device can serve as a basic memory element, delaying the output by one clock count with respect to the input
D Flip-Flop
The D ip- op is an extension of the data latch that utilizes two RS ip- ops, as shown in Figure 146 In this circuit, a clock is connected to the enable input of each ip- op Since Q1 sees an inverted clock signal, the latch is enabled when the clock waveform goes low However, since Q2 is disabled when the clock is low, the output of the D ip- op will not switch to the 1 state until the clock goes high, enabling the second latch and transferring the state of Q1 to Q2 It is important to note that the D ip- op changes state only on the positive edge of the clock waveform: Q1 is set on the negative edge of the clock, and Q2 (and therefore Q) is set on the positive edge of the clock, as shown in the timing diagram of Figure 146 This type of device is said to be edge-triggered This feature is indicated by the knife edge drawn next to the CLK input in the
