FAQ about Logic - Counters, Dividers
-
1. 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.

2. 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. -
3. What is a counter integrated circuit?
Counter integrated circuit is a digital integrated circuit used to record the number of input pulse signals. It is widely used in digital circuits and control systems and has many types and functions.
Definition and function
Counter integrated circuit is a circuit used to record the number of input pulse signals, usually used for time delay, frequency measurement, frequency division and other functions. It can be controlled and called by program in embedded systems to achieve complex functions.
Type
MCU internal counter: In a single-chip microcomputer, there are usually multiple internal counters that can be controlled and called by program, which are often used for time delay, PWM output, capturing external events, etc.
74 series counter: A counter integrated circuit based on TTL (transistor-transistor logic) technology can realize simple counting, frequency division, frequency measurement and other functions. Common 74 series counters include 74LS90, 74LS93, 74LS161, 74LS163, etc.
Asynchronous counter: A counter circuit based on gate-level triggers that realizes simple binary counting, but is slow and prone to timing jitter, and is less used.
Synchronous counter: A counter circuit based on latches and clock signals, with high speed and data stability, commonly used for high-bit, high-precision counting, such as 74LS163, 74LS169, etc.
