DESCRIPTION HCF4089B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4089B is a low power 4-bit digital rate multiplier that provides an output pulse rate that is the clock input pulse rate multiplied by 1/16 times the binary input. For example, when the binary input number is 13, ther will be 13 output pulses for every 16 input pulses. HCF4089B has an internal synchronous 4-bit counter, which, together with one of the four

binary inputs bits, produces pulse trains as shown in the timing diagram. If more than one binary input bit is high, the resulting pulse train is a combination of the above separate pulse trains. This device may be used to perform arithmetic operations (add, subtract, divide, raise to a power), solve algebrical and differential equations, generate natural logarithms and trigonometric functions, A/D and D/A conversions, and frequency division.
