The J and K pins are the input pins for the Flip-Flop and the Q and Q bar pins are the output pins. The below circuit shows a typical sample connection for the JK flip-flop So if you are looking for a IC for latching purpose or to act as a small programmable memory for you project then this IC might be the right choice for you.Īs told earlier we have two JK flip flops in this IC, the IC is powered by +5V typically the minimum and maximum input and output voltage for the input (J,K) pins and the output (Q, Q bar) pins are discussed in the specifications above. The JK flip flop is considered to be more suitable for practical application because of its truth table that is the output of the flip flop will be stable for all types of inputs. More than one Flip Flop can be used in series to act as an EEPROM for holding small amount of data. The flip-flops are also called as latching devices meaning it can remember one single bit of data and latch the output based on it, due to this property they are commonly used as shift registers, control registers, storage registers or where ever a small memory is required. The JK flip flops are considered to be the most efficient flip-flop and can be used for certain applications on its own. The term JK flip flop comes after its inventor Jack Kilby. it has two JK flip flops inside it and each can be used individually based on our application. The SN7476 is a dual in-line JK flip flop IC, i.e. Available in 14-pin PDIP, GDIP, PDSO packages.When Clear is high the flip flop will set Q=0 and not Q=1 When Preset is high the flip flop will set Q=1 and not Q=0 These pins must be provided with clock pulse for the flip flop
