What is a 74LS74?

What is a 74LS74?

The 74LS74 is a dual positive-edge triggered D-type flip-flop which can be configured to perform as a divide-by-two counter. But to do so, ! PR and ! CLR must be tied together HIGH (to logic-1), NOT-Q connected to D (feedback loop) and the clock signal applied directly to CLK. The output is present on Q.

How many transistors are in ad flip flop?

The D flip-flop uses two D latches and a NOT gate, or 46 transistors.

Which IC is used for JK flip flop?

MC74HC73A
The IC used is MC74HC73A (Dual JK-type flip-flop with RESET). It is a 14 pin package which contains 2 individual JK flip-flop inside.

Which IC is used for SR flip-flop?

The IC used is SN74HC00N (Quadruple 2-Input Positive-NAND Gate). It is a 14 pin package which contains 4 individual NAND gates in it. Below is the pin diagram and the corresponding description of the pins.

What is a SR latch?

An SR latch made from two NAND gates. An SR latch (Set/Reset) is an asynchronous device: it works independently of control signals and relies only on the state of the S and R inputs. SR latches can also be made from NAND gates, but the inputs are swapped and negated. In this case, it is sometimes called an SR latch.

How many inputs does the RS latch have?

two inputs
This device consists of two inputs, one called the Set, S and the other called the Reset, R with two corresponding outputs Q and its inverse or complement Q (not-Q) as shown below.

What are the applications of 74ls74?

Applications of 74LS74 1 Used as Shift Registers 2 Memory/Control Registers 3 Buffer Circuits 4 Sampling Circuits 5 Latching devices More

What is the working of 74ls74 flip-flop?

These flip-flops are widely used in communication systems and computers. The working of 74LS74 is simple and straight forward. In order to activate the chip, power the GND and Vcc pin of the chip. In this dual D flip-flop, each flip-flop works independently.
