The "CD4013BE" is a part of the CD4000 series of integrated circuits (ICs) produced by Texas Instruments. It is a dual D-type flip-flop IC, which is often used in digital circuits for storage, control, and memory applications.
Pinout and Package Information
The CD4013BE typically comes in a 14-pin Dual In-line Package (DIP-14) form factor. Below is a detailed description of the pin functions, as well as a list of pin numbers and their corresponding functions:
Pin Number Pin Name Function Description 1 Q1 Output of the first flip-flop. Provides the stored logic state of the flip-flop. 2 Q1' Inverted output of the first flip-flop. Represents the opposite state of Q1. 3 CLK1 Clock input for the first flip-flop. Determines when the state of the flip-flop changes. 4 D1 Data input for the first flip-flop. The value presented here is stored on the rising edge of the clock. 5 RESET1 Reset input for the first flip-flop. Forces the flip-flop to its initial state when activated. 6 VSS Ground pin. Connects to the ground of the circuit (0V). 7 VDD Power supply pin. Connects to the positive voltage of the circuit (typically +5V or +3.3V). 8 D2 Data input for the second flip-flop. The value presented here is stored on the rising edge of the clock. 9 CLK2 Clock input for the second flip-flop. Determines when the state of the second flip-flop changes. 10 RESET2 Reset input for the second flip-flop. Forces the flip-flop to its initial state when activated. 11 Q2 Output of the second flip-flop. Represents the stored logic state of the second flip-flop. 12 Q2' Inverted output of the second flip-flop. Represents the opposite state of Q2. 13 NC No connection (this pin is not used and is left unconnected in most designs). 14 NC No connection (similar to pin 13, this pin is unused).Key Functions:
Q1 and Q1' are the outputs for the first flip-flop. Q2 and Q2' are the outputs for the second flip-flop. CLK1 and CLK2 are the clock inputs that trigger state changes in their respective flip-flops. D1 and D2 are the data inputs for each flip-flop, used to store a logic state on the rising edge of the clock. RESET1 and RESET2 are the reset pins that initialize each flip-flop to a known state, typically logic low (0).FAQ (Frequently Asked Questions)
What is the CD4013BE? The CD4013BE is a dual D-type flip-flop IC in a 14-pin package, used for data storage in digital circuits.
How many pins does the CD4013BE have? The CD4013BE has 14 pins in total, packaged in a Dual In-line Package (DIP-14).
What is the purpose of the Q1 and Q1' pins? Q1 is the output of the first flip-flop, and Q1' is its inverted output.
What is the function of the CLK1 and CLK2 pins? CLK1 and CLK2 are the clock inputs for the first and second flip-flops. They trigger state changes on the rising edge.
What does the RESET1 and RESET2 pins do? These reset pins force their respective flip-flops to a known initial state (typically logic low) when activated.
What is the difference between Q1 and Q1'? Q1 is the direct output of the flip-flop, while Q1' is its complementary (inverted) output.
Can the CD4013BE be used with a 3.3V power supply? Yes, the CD4013BE can operate with a power supply between 3V and 15V, with 5V being typical.
What is the purpose of the D1 and D2 pins? D1 and D2 are the data inputs for the first and second flip-flops. The data presented on these pins is stored on the rising edge of the clock.
What type of logic does the CD4013BE use? The CD4013BE uses positive-edge triggering logic for data storage in its flip-flops.
What is the package type for the CD4013BE? The CD4013BE comes in a 14-pin Dual In-line Package (DIP-14).
How is the CD4013BE initialized after power-up? The flip-flops are initialized to a low state (0) after power-up, unless a reset is applied.
Can the CD4013BE be used in synchronous circuits? Yes, the CD4013BE is ideal for use in synchronous circuits, as it stores data on the clock edge.
What are the typical applications of the CD4013BE? The CD4013BE is commonly used in timing circuits, memory storage, and state machines.
Is there a limit to how many CD4013BE ICs can be used together? There is no fixed limit. However, practical constraints like power consumption and board space may affect how many can be used in a design.
What should be done if the CD4013BE is not responding to clock signals? Check the power supply, clock signal integrity, and reset conditions. Ensure that the clock is properly connected and the reset pin is not held active.
Can the CD4013BE be used in high-speed circuits? While the CD4013BE is suitable for many applications, it is not designed for ultra-high-speed circuits. Its speed is moderate for most general-purpose logic tasks.
What is the voltage tolerance of the CD4013BE? The CD4013BE can tolerate a voltage range of 3V to 15V at its VDD pin.
Can the CD4013BE be used with a 5V supply? Yes, the CD4013BE operates well with a 5V power supply, which is common in many digital systems.
Is the CD4013BE suitable for both logic high and low level signals? Yes, the CD4013BE can handle both logic high (typically 3V to 15V) and logic low signals.
What happens if a pin is left unconnected? If a pin like RESET1 or RESET2 is left unconnected, it may lead to undefined behavior, so it's recommended to either connect these pins to ground or use them as needed.
