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.

APPLICATION NOTES For words of more than 4 bits, HCF4089B device may be cascaded in two different modes : an ADD mode and a MULTIPLY mode. TWO HCF4089B'S CASCADED IN THE "ADD" MODE WITH A PRESET NUMBER OF 189

In the ADD mode some of the gaps left by the more significant unit at the count of 15 are filled in by the less significant units. For example, when two units are cascaded in the ADD mode and programmed to 11 and 13, respectively, the more significant unit will have 11 output pulses and the other unit will have 13 output pulses for every 256 input pulses for a total of : 11 13 189 + = 16 256 256

TWO HCF4089B'S CASCADED IN THE "MULTIPLY" MODE FOR MULTIPLICATION OF TWO VARIABLES A AND B WITH LOOP CIRCUIT CONTROL

A B 1 N When the loop stabilities rate R2 = rate R3, thus fclock( · ) = fclock ( · ) therefore N = AB 16 16 16 16
