Logic - Counters, Dividers

Digital logic integrated circuits are devices known as counter and divider ICs that count the number of logic transitions that pass through their inputs. These devices then display the total count using multiple parallel outputs while producing a single output signal transition in response to an integer number of input signal transitions. A counter is an integrated circuit or an electronic device that stores (and occasionally displays) the number of times a specific event or process has occurred in digital logic and computing, frequently concerning a clock. The most typical kind is a sequential digital logic circuit with several output lines and a clock-input line.

How Do Logic Counters, Dividers Work?

Although logic dividers are integrated circuits (ICs) that divide an input signal's frequency by a predetermined division ratio. An output from the Frequency Divider component is the clock input divided by the chosen factor. It uses the Frequency Divider to split another signal's frequency or as a clear clock divider for Universal Data Bank (UDB) components.

Significance of Logic Counters and Dividers:

Logic counters are integrated circuits (ICs) that keep track of events in digital systems like computers. Logic counters have memory because they must recall previous states. Bistable devices or bistable multivibrators known as flip-flops make up logic counters.

Logic dividers carry out the supply voltage, the operational current, clock frequency, and power dissipation of logic divisions can differ. Supply voltages include intermediate voltages ranging from 1.2 v to 4.5V. They also vary from - 5 V to 5 V and the operating current is the least current required to operate an active chip.

Types of Logic Counters and Dividers:

There are several types of Logic Counters implemented according to the requirement, but the most common types are stated below:

• Synchronous counters
• Asynchronous counters
• Bi-quinary counters
• Decade counters
• Decade counters
• MOD-N counters

In addition to this, there are two types of logic dividers implemented according to their functionality:

Fixed Dividers - They are divided in a fixed ratio that consumers cannot alter.

Programmable Dividers - These dividers have a maximum division ratio and are programable to utilize any division ratio.

Applications of Logic Counters and Dividers:

Logic counters and dividers are widely used in the following devices:

• Digitized clocks
• Analog to digital converters (A2DCs)
• Measurement of time
• Frequency counters

Furthermore, dividers are also employed in frequency synthesizers in various electronic applications. Phased locked loops (PLLs) are circuits in which voltage-controlled oscillators provide input signals to logic divisions, which then divide the signals by a division ratio and output the results to a phase comparator.
