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 kind of IC is used for counters?
Common counter ICs include the following:
74LS163: This is a 4-bit synchronous counter designed with a gate-level trigger, which can be used for counting, frequency division, waveform generation and other circuits. It is characterized by a simple input port, expandable counting bit number, and wide application.
74LS169: This is a 4-bit synchronous reversible counter that can count in both positive and negative directions. It can be used in circuits such as time measurement, electronic clocks, timers, and electronic games. Its feature is that the counting direction is controllable, and it can realize forward and reverse counting and conversion.
74LS190: This is a resettable 4-bit synchronous counter that can realize binary counting and can be used in circuits such as frequency dividers, frequency meters, timers, and position indicators. Its features are resettable counting, zero clearing function, simple and practical.
CD4017: This is a very popular frequency divider and counter chip with a built-in 10-bit counter. A single output pin outputs a high level, which can realize Morse code generators, LED running lights, automatic line patrol cars and other circuits. Its features are stable output level and flexible and diverse applications.
CD4040: This is a 12-bit binary counter that can realize binary counting of 1-4096 and can be used in circuits such as timers, frequency dividers, and pulse generators. Its features are strong scalability, variable counting digits, and wide application fields.
