1 / 13 page  HCC/HCF4089B BINARY RATE MULTIPLIER DESCRIPTION . CASCADABLE IN MULTIPLES OF 4-BITS . SET TO ”15” INPUT AND ”15” DETECT OUT- PUT . QUIESCENT CURRENT SPECIFIED TO 20V FOR HCC DEVICE . STANDARDIZED SYMMETRICAL OUTPUT CHARACTERISTICS . INPUT CURRENT OF 100nA AT 18V AND 25 °C FOR HCC DEVICE . 100% TESTED FOR QUIESCENT CURRENT . MEETS ALL REQUIREMENTS OF JEDEC TEN- TATIVE STANDARD N o. 13A, ”STANDARD SPECIFICATIONS FOR DESCRIPTION OF ”B” SERIES CMOS DEVICES” 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.
