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 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. -
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.
