In this article, a brief introduction to the application field and working principle of the MC74HC390AFELG is given in order to provide an overview of its utility.

Application Field

This logic device is used for a wide array of applications involving logic. It finds its use in projects ranging from industrial or commercial to consumer electronics. For example, MC74HC390AFELG can be used in projects involving media and communications, such as for sound output, user interface control, and data transmission. Additionally, it is commonly used in motor control and process automation, like for controlling robot movements in industrial plants for uniform production. This device can also be used for standard microprocessor designs, 3D printer designs, and digital signage applications. As a result, MC74HC390AFELG serves as a fundamental tool in enabling efficient production and project management.

Working Principle

MC74HC390AFELG is a dual 4-bit general-purpose ripple binary counter. The device has two independent 4-bit counter and two clock inputs (A and B). At each clock input edge, the count progresses by one. For example, at the rising edge of the clock signal A, the first counter progresses by one, while at the rising edge of the clock signal B, the second counter progresses by one. Thus, different count values can be achieved. It has an asynchronous reset pins, which can be used to reset the entire 4-bit counters to \'0000\'. It also features a carry output for cascading the output of each counter.

Moreover, the device is packaged in a 16-pin SOIC, TSSOP, or PDIP package. It is designed to operate from 0°C to 70°C temperature range. The device is also designed using CMOS technology, which allows it to directly drive over a wide voltage range. It operates at a power supply of either 4.5V to 5.5V for TTL and 0V to 3.3V for CMOS. The device also has a low power supply current of 6.0mA (max). It is also available in various configurations to suit the desired application.

MC74HC390AFELG is a handy logic device that provides a reliable and flexible logic platform to build logic-intensive desgins. Its wide range of applications, readily available packages, and low power consumption make it an ideal choice in a variety of projects. Coupled with other logic devices, MC74HC390AFELG provides a versatile and reliable logic platform.
