What is a 4013 chip?

What is a 4013 chip?

The 4013 contains two independent D-type flip-flops with asynchronous set/reset inputs. Whenever the set or reset pins go high, the appropriate output is expressed immediately on the outputs. When set and reset are low, the output shows the data at the input at the time of the last low-to-high clock transition.

What is a flip-flop chip?

A flip-flop is a device which stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”. Such data storage can be used for storage of state, and such a circuit is described as sequential logic in electronics.

What is 74ls74?

74LS74A flip-flop IC carries the Schottky TTL circuitry to generate high-speed D-type flip-flops. Every flip-flop in this chip comes with individual inputs, and also complementary Q and Q`(bar) outputs. Flip-Flops are normally considered as the basic building blocks of modern digital electronics.

What is an SR flip flop?

SR flip-flop is a gated set-reset flip-flop. The S and R inputs control the state of the flip-flop when the clock pulse goes from LOW to HIGH. The flip-flop will not change until the clock pulse is on a rising edge. When both S and R are simultaneously HIGH, it is uncertain whether the outputs will be HIGH or LOW.

How do I use IC 4017?

The clock pulses generated at the output of the IC 555 timer (PIN-3) are given as an input to IC 4017 through PIN-14. Whenever a clock pulse is received at the clock input of the IC 4017 counter, the counter increments the count and activates the corresponding output PIN.

Why is it called flip-flop?

All you need to do to figure out why we call them “flip-flops” is to walk around in a pair of them for just a little while. Because of how they’re made, the rubber soles slap against the bottom of your feet as you walk, making a flip-flop, flip-flop sound. The name “flip-flop” is thus an example of onomatopoeia.

Which IC is used for JK flip-flop?

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. Above is the pin diagram and the corresponding description of the pins.

How many flip flops are in the 7474 IC?

The 74LS74 device contains two independent positive-edge-triggered D flip-flops with complementary outputs.

Which IC is used for D flip flop?

Here, the given circuit demonstrates the operation of D flip-flop. The flip-flop is built using four 2 input NAND gates, one NOT gate and clock pulse generator is built using multivibrator chip IC NE555.

What is RS and JK flip flop?

The JK flip flop is a universal flip flop having two inputs ‘J’ and ‘K’. In SR flip flop, the ‘S’ and ‘R’ are the shortened abbreviated letters for Set and Reset, but J and K are not. The J and K are themselves autonomous letters which are chosen to distinguish the flip flop design from other types.

What is a CD4017?

The CD4017 is a CMOS Decade counter IC. CD4017 is used for low range counting applications. It can count from 0 to 10 (the decade count). The circuit designed by using this ic will save board space and also time required to design the circuit. CD4017 is as ‘Johnson 10 stage decade counter’.

Why is 555 called timer?

The 555 Timers name comes from the fact that there are three 5kΩ resistors connected together internally producing a voltage divider network between the supply voltage at pin 8 and ground at pin 1.

Who invented flip-flop?

As for the modern-day flip-flop, its origins trace back to Japan, said Elizabeth Semmelhack, curator of the Bata Shoe Museum in Toronto. During World War II, Japan was big into rubber production. It took over rubber tree plantations across Southeast Asia.

What is 7474 IC?

The Integrated-Circuit D Flip-Flop (7474) The 7474 is an edge-triggered device. The Q output will change only on the edge of the input trigger pulse. The small triangle on the clock (Cp) input of the symbol indicates that the device is positive edge-triggered. The D and the clock inputs are synchronous inputs.

What is a 7473 IC?

The IC 7473 or mostly known as 74LS73 is a dual JK flip Flop logic gate IC. It is a negative edge-triggered IC. It has two independent JK Flip Flops. They have complementary outputs. These Flip Flops are negative edge triggered.
