A counter IC (integrated circuit) are electronic devices that are designed for counting externally input clock pulses.
This IC operates by reading the counter data output via the I2C-bus serial interface from a microcontroller or another system. It has a configuration of a 24-bit binary-up counter and can count from 0 to 24 bit and also operates at a ultra-low current consumption in comparison to that of a event counter in a microcontroller.
Counter ICs have a range of different types of configurations such as;
Shift registers - Shift registers are a sequential logic device made up of a cascade of flip-flops, through which a sequence of bits are ’shifted’. These devices are commonly used to convert between serial and parallel interfaces.
Clock Generator - Clock Generators produces a clock signal for use in synchronizing a circuit's operation.
Dividers - Dividers also known as clock dividers provide an output clock signal that is a divided frequency of the input.
There are also various types of counter types such as BCD, Binary, Decade, Divide by N and Octal.
Counter ICs are widely used in an array of applications such as;
