June 1989

The HCC4089B (extended temperature range) and

HCF4089B (intermediate temperature range) are

monolithic integrated circuit available in 16-lead

dual in-line plastic or ceramic package.

The HCC/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, there will be 13 output pulses for every

16 input pulses.

The HCC/HCF4089B has an internal synchronous

4-bit counter which, together with one of the four bi-

nary input bits, produces pulse trains as shown in

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 algebraic and differential equations,

generate natural logarithms and trigonometric func-

tions, A/D and D/A conversions, and frequency di-

vision.
