Logic integrated circuits are a type of device used to build digital systems and aid in their functionality. One such conventional integrated circuit is SN74LS390NG4, which is categorized as a logic counter and divider. This article will discuss SN74LS390NG4\'s application field and working principle.

SN74LS390NG4 has a wide range of applications in many industrial sectors. It is a type of BCD or Binary-Coded Decimal counter that is used to carry out critical functions such as counting, counting frequency, timing, and reading frequency at an input signal. It is mainly employed for counters, frequency dividers, analogue-to-digital converters, and other types of digital systems. Due to its robust design and performance, it is incredibly popular in many industries such as automotive, power electronics, medical systems, wearable electronics, and others.

The working of SN74LS390NG4 is based on a series of synchronous up/down counters that is activated by two (up/down) control inputs. These two control inputs are basically for data direction and loading, which is often dependent on external sources and can be based on both positive and negative edge triggers. The loading of SN74LS390NG4 is flexible and can either be synchronous or asynchronous.

SN74LS390NG4 also contains four 4-bit counters, each of which functions independently in the context of 4-bit binary or BCD outputs. Each of the counters has four synchronization inputs and two clock inputs, meaning that each counter can run at a different rate and count at a different frequency. In addition, if one of the four counters reaches its maximum count, the NG4 counter simultaneously transfers its content to the next counters, enabling the cascade of counters. This is useful for creating multiplexing systems where several counters must be combined together.

In addition to its flexible loading and synchronous operation, SN74LS390NG4 is designed to remain stable during multiplex operations. This supports the ability to control the speed of the counters, while ensuring that the output remains stable during multiplex operations. Furthermore, its bidirectional outputs are designed to either transmit or receive data depending on its current state. This makes it an ideal device to use in applications where data must be collected and transmitted in an efficient manner.

SN74LS390NG4 is highly versatile and is used for various industrial and commercial applications. It is widely used for counting pulses, frequency dividers, digital control systems, and other digital systems. It is also used for synchronized counting, multitasking, multiplexing, and data transmission. SN74LS390NG4\'s exceptional design and performance make it an ideal choice for many industrial applications.

In conclusion, SN74LS390NG4 is a synchronous up/down counter and divider that has a wide range of applications in many industrial sectors. Its versatile design, performance, and two control inputs make it ideal for various industrial and commercial applications, such as counting pulses, frequency dividers, digital control systems, and other digital systems. Its ability to remain stable during multiplex operations, while still providing accurate outputs, makes it an ideal solution for many applications.
