CD4089 Binary Rate Multiplier IC DIP-16 (CD4089 DIP IC)
The CD4089 is a CMOS binary rate multiplier IC that generates an output pulse rate that is a binary fraction of the input clock frequency. It accepts a 4-bit binary input value and produces an output frequency equal to the input clock multiplied by the selected binary fraction from 0 to 15 sixteenths.
This IC is widely used in frequency synthesis, digital to analog conversion, pulse width modulation, and arithmetic operations where a precise fractional frequency output is required. It is commonly used in industrial control systems, digital communication circuits, Arduino projects, and electronics where controlled pulse rate generation and frequency scaling are needed.
