CD4013 circuit

The CD4013 is a dual D flip-flop that operates on the rising edge of the clock signal. Its internal block diagram and pin configuration are provided. This device is part of the standard model C043 and the GB model CC4013. Additionally, it has substitutable or interchangeable models such as TC4013, MC14013, C073, SG822, and others.

The CD4013 dual D flip-flop is a versatile digital memory circuit used for storing binary information. Each flip-flop has two inputs, D (data) and CLK (clock), and two outputs, Q and Q' (complement of Q). The flip-flop captures the value present at the D input on the rising edge of the CLK signal, transferring this value to the Q output. The Q' output always reflects the inverse of the Q output.

The internal structure of the CD4013 consists of multiple stages of logic gates configured to form the flip-flop functionality. The device operates with a supply voltage range of 3V to 15V, making it suitable for various applications in both low and high voltage environments. The propagation delay between the clock input and the output state change is typically around 50 nanoseconds at a supply voltage of 5V, which makes it suitable for moderate-speed applications.

Pin configuration is critical for proper integration into circuits. The CD4013 has 14 pins, with the primary pins being:
- Pins 1 and 2: D input and CLK input for the first flip-flop.
- Pins 3 and 4: Q output and Q' output for the first flip-flop.
- Pins 5 and 6: D input and CLK input for the second flip-flop.
- Pins 7 and 8: Q output and Q' output for the second flip-flop.
- Pins 11, 12, 13, and 14 are used for power supply and ground connections.

The CD4013 is widely used in digital circuits for applications such as data storage, state machines, and frequency division. Its ability to interface with various logic families enhances its applicability in diverse electronic designs. The interchangeable models (TC4013, MC14013, etc.) offer flexibility in sourcing components while maintaining compatibility with the original design specifications.CD4013 dual D flip-flop on the rising edge.
