The CD4013BE is a dual D-type flip-flop integrated circuit (IC) that is commonly used in electronic circuits for storing binary data. Flip-flops are digital circuits that can hold a single bit of data and are used for storing, buffering, and transferring data in digital systems. The CD4013BE consists of two D-type flip-flops that can operate independently or can be connected together to form a single 4-bit register. It has two input terminals (D1 and D2) and two output terminals (Q1 and Q2) for each flip-flop. The flip-flops can be clocked using the CLK1 and CLK2 inputs, and the data can be stored or transferred on the rising edge of the clock signal. The CD4013BE comes in a DIP-14 package, which is a dual in-line package with 14 pins. It is widely used in digital circuits, such as counters, shift registers, and memory devices.

This is a Dual D-type flip-flop IC. Every pulse will invert the state of the output.
