The basic D Flip Flop has a D (data) input and a clock input and outputs Q and Q (the inverse of Q). Optionally it may also include the PR (Preset) and CLR (Clear) control inputs.The truth table and diagram001101PRECLRDCLKQQ...
we shall only consider a very simple type of flip-flop called aD-flip-flop. A master-slave D-flip-flop is built from two SR-latches and some gates. Here is the circuit diagram:
In the SR flip flop circuit, from each output to one of the other NAND gate inputs, feedback is connected. So, the device has two inputs, i.e., Set 'S' and Reset 'R' with two outputs Q and Q' respectively. Below are the block diagram and circuit diagram of the S-R flip ...
is quite easy to understand if you draw a pulse diagram for it and analyze the flip-flop's output over time. When the encoder disk spins clockwise, the Q output goes high; when counterclockwise, the Q goes low. Follow-up question: comment on the notation used for this circuit's output...
master-slave-flip-flop-circuit Master-Slave FF Working Whenever the CLK pulse goes to high which means 1, then the slave can be separated; the inputs like J & K may change the condition of the system. The slave FF can be is detached until the CLK pulse goes to low which means to ...

PURPOSE:To attain stable operation even with an I<2>L as a logical circuit realizing element by constituting a binary counter having a small inter-stage delay with an FF circuit of a unit stage. CONSTITUTION:In FF circuits 1000, 2000 constituting the unit stage, an output signal of a gate...
NAND Gate SR Flip Flop Test Circuit Turns out you can build these out of NAND gates too. There is a vital difference though: in the case of a NAND gate, the inputs are active low. Both schematics are offered: the one using SPDT switches shown above andone using tactile buttons. There...
Simple set reset flip flop circuit made using a 7474 74HC74 integrated circuit IC What is 74HC74? The74HC74is aD-type flip-flopwith dual positive edge triggering. They have individual data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ output...
