Logic - Flip Flops: HEF4013BP,652

Flip-flops, at their core, are circuit components that take an input, and based on that input, set an output. This output is then amplified, creating an amplified input for the next flip-flop in the chain. HEF4013BP,652 is a multi-purpose flip-flop from the HEF4000 logic family. It is capable of acting as a single-level NAND gate and as a bistable (flip-flop) type circuit. This article will be focusing on the application field and working principle of HEF4013BP,652.

Application Fields

As a multi-purpose flip-flop, HEF4013BP,652 can be used in a wide variety of applications. In digital circuit design, the flip-flop can be used to store binary information, acting as a data latch or flip-flop cell. Likewise, it can be used as a set-reset type register or as a data transfer and control element in computers and other digital logic circuits. One advantage of using HEF4013BP,652 is its wide operating voltage range of 5V to 15V, which provides flexibility and allows it to operate with different power sources. Furthermore, its low power dissipating characteristics allow it to achieve high power-saving efficiency in digital systems.

Working Principle

The HEF4013BP,652 is a single one-shot, dual flip-flop. It consists of two individual NAND gates with each gate connected together to form a single flip-flop. Each NAND gate is composed of two cross-coupled transistors. The dual inverting NAND gates form a flip-flop latch with two inputs and two outputs. The first input is called the clock (R) and the second input is called the reset (S). The first output is the inverse of the other output and is known as the Q not (QN) output.

When the clock and reset inputs are low, the output of the flip-flop latch is briefly High. After the pulse, the Gate output reverts to the position it was previously held in. If the latch is set "high" and a pulse is applied to the reset input, the output will remain low. Conversely, if the latch is low and a pulse is applied to the clock input, the output will remain High. The two cross coupled transistors provide a feedback path which enables the flip-flop behavior. Thus, the HEF4013BP,652 can be used as a data storage element, or as a set-reset type register, to store binary information in digital systems.

Conclusion

The HEF4013BP,652 is a highly versatile flip-flop element with a wide operating voltage range and low power-dissipation characteristics. It can be used as a single-level NAND gate and as a bistable (flip-flop) type circuit. As a data storage element, it can be used to store binary information or used as a set-reset type register. Furthermore, its two cross coupled transistors provide a feedback path which enables the flip-flop behavior.
