Application of M74HC390D

Counters, Dividers are widely used in many fields such as electronic equipment, communication system, control system and computer technology. In electronic equipment, they are used to realize key functions such as timing control, frequency measurement and pulse signal generation. In the communication system, it is used for synchronous signal processing, clock recovery, carrier frequency tracking and other scenarios. In the control system, counters and dividers are the core components of automatic control, accurate measurement and motion control. In addition, in computer technology, they are also a key component of core processors such as cpus and Gpus to execute instructions internally, manage resources, and control the flow of data.

M74HC390D Classification

Logic - Counters, Dividers

Counters, Dividers are an important part of the logic circuit in the integrated circuit, which is used to realize the function of digital signal counting and division. A counter can increment or decrement the count in a predetermined manner, and is usually composed of basic units such as Flip-Flops, Adders, and Logic Gates. Its design principle is based on the increasing or decreasing law of binary numbers, and the count is updated by triggering the Clock Signal. The divider is a circuit that divides the input signal, which can divide or delete the input signal according to the set divisor, and reduce the input frequency according to a fixed proportion, that is, divide the input pulse. It is widely used in digital signal processing, clock generation, frequency synthesis and other fields. The combination of counter and divider can realize complex timing control and data processing functions, and has the characteristics of high precision, high stability and programmability.

FAQ about Logic - Counters, Dividers

  • 1. What is a counter in digital logic design?

    A counter is a commonly used sequential logic circuit in digital logic design, mainly used to count the number of pulses, so as to realize functions such as measurement, counting, frequency division and control. A counter consists of a basic counting unit and some control gates, and these counting units are usually composed of triggers (such as RS triggers, T triggers, D triggers and JK triggers).
    Classification of counters
    Synchronous counters and asynchronous counters: classified according to whether the triggers flip at the same time.
    Adder counters, subtractor counters and reversible counters: classified according to the increase and decrease of numbers during the counting process.
    ‌Binary counters and decimal counters: classified according to the counting system.

  • 2. What is a counter in a logic circuit?

    A counter is a logic circuit that realizes counting operations, mainly used to count the number of pulses to realize the functions of measurement, counting and control, and also has frequency division functions. A counter consists of a basic counting unit and some control gates, and these counting units are composed of a series of triggers with information storage functions, such as RS triggers, T triggers, D triggers and JK triggers.

  • 3. What is a counter IC?

    A counter IC is an integrated circuit (IC) that can count external input clocks. It usually sends counting data through the I2C-bus interface and is suitable for various measuring devices, infrastructure-related measuring instruments, entertainment equipment, life counters, etc. The basic function of a counter IC is to count the input pulse signal. The state of its output port changes with the number of input pulse signals. When the maximum value is reached, the output state returns to zero.
    Working principle of counter IC
    The basic working principle of counter IC is to count the external input clock signal. It usually consists of a trigger, an adder, and a clock control circuit. Counter IC has two working modes: synchronous and asynchronous. Synchronous counters work under a unified clock signal and update the output state at the end of each clock cycle; asynchronous counters reset the output state of the counter by receiving a special clear signal.
