Overview of Dual D Flip-Flop
A digital electrical circuit called a D (or Postpone) Flip Flop (Figure 1) is used to delay the change of state of its output signal (Q) until the next rising edge of a clock timing input signal occurs.
A D-type latch operates with a delay in input by one clock cycle. Thus, by cascading many D-type flip-flops delay circuits can be created, which are used in many applications such as in digital television systems.

D Flip-Flop

Truth Table
The D flip flop is the most important flip flop from other clocked types. It ensures that at the same time, both the inputs, i.e., S and R, are never equal to 1. The Delay flip-flop is designed using a gated SR flip-flop with an inverter connected between the inputs allowing for a single input D (Data).
What is CD4013?
The CD4013 device consists of two identical, independent data-type flip-flops. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q outputs. A monolithic complementary MOS (CMOS) integrated circuit containing N- and P-channel enhancement mode transistors, the CD4013 dual D flip-flop is a monolithic complementary MOS (CMOS) integrated circuit. Data, set, reset, and clock inputs, as well as "Q" and "Q" outputs, are all independent on each flip-flop.

The parameter "Current - Quiescent (Iq)" in electronic components refers to the amount of current consumed by a device when it is in a quiescent or idle state, meaning when it is not actively performing any tasks or operations. This parameter is important because it represents the baseline power consumption of the device even when it is not actively being used. A lower quiescent current (Iq) value is desirable as it indicates that the device is more energy-efficient and will consume less power when not in use, which can help extend battery life in portable devices and reduce overall power consumption in electronic systems. Designers often pay close attention to the quiescent current specification when selecting components for low-power applications or battery-operated devices.

SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.

RoHS Compliant - Lead Free
Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.

CD4013 Circuit
To power the 4013, we connect VSS, pin 8, to ground and feed 5V to VDD, pin 16.
A clock signal is connected to the 4013's clock, which is pin 3. We connect a clock signal to the clock of the 4013, which is pin 3. This clock pin can be obtained from several sources such as a frequency generator or a 555 timer chip or a 4046 chip. It can even be obtained from a 7414 Schmitt trigger inverter chip.
A pull-down resistor is connected to each of the three input pins, the data pin, set pin, and reset pin. When the pushbutton is not pressed, the pin is generally in the LOW condition. When we press down on the pushbutton, it switches to HIGH mode. So all the pins have a value of 0 at first, but when we press the pushbutton, it changes to a value of 1.

CD4013 Circuit
How to use CD4013?
You must first connect the VDD pin to the positive supply terminal and the GND pin to the negative supply terminal before using any of the D flip-flops gates in the device.
A power supply voltage of 3V to 15V can be used. The 4013 chip supports up to 20V in some versions. For accurate values, consult the datasheet for your chip's version.

CD4013 Diagram
The D (data) pin is where you input the data you want to store in the flip-flop.
Provide a signal that goes from LOW to HIGH on the CLK pin to store the data from the D pin to the output pin Q.
The output pin Q is always the opposite of pin Q.
Use the S (set) pin to force the output pin HIGH.
Use the R (reset) pin to force the output pin LOW.

CD4013 Manufacturer
On Semiconductor (Nasdaq: ON) is a manufacturer engaging itself in reducing energy use. It features a comprehensive portfolio of power, signal management, and logic, custom solutions that are energy efficient. It acts as a world-class supply chain with high reliability and a network of manufacturing facilities, sales, offices, and design centers in key markets through North America, Europe, and the Asia Pacific regions.
How does CD4013 work?
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 CD4013 used for?
The CD4013 or IC-4013 is a CMOS logic chip with two D-Type (DATA) Flip-flops. A clock pulse flow to C (clock pin), will store the data at the D input. Connect clock and both Q output to make a toggle flip-flop for counting.
What is clock signal in flip flops?
A clock pulse is a time-varying voltage signal applied to control the operation (triggering) of a flip flop. For example, if a clock pulse is of frequency 1 Hz, the voltage it will supply will oscillate between X Volts and Y Volts(X and Y are any dc voltages), and this change occurs every half second.
What happens if flip-flop has no clock?
Flip flops are memory devices and clocks are used so that they respond to external stimuli. When the clock is active only then the changes in the input will be registered. So, if you permanently disable the clock, the flip flop will permanently retain the previous input.
Is D flip-flop edge triggered?
The D flip-flop is an edge-triggered device that transfers input data to Q on a clock rising or falling edge. Data Latches are level-sensitive devices such as the data latch and the transparent latch.
