CD4089BMS, CMOS Binary Rate Multiplier

of ‘B’ Series CMOS Devices” In the Multiply mode the fraction programmed into the ﬁrst rate multiplier is multiplied by the fraction programmed into the second multiplier.

Thus the output rate will be 11 16 x 13 16 = 143 256 Applications * Numerical Control * Instrumentation

CD4089BMS December 1992 CMOS Binary Rate Multiplier conjunction with an up/down counter and control logic used to perform arithmetic operations (adds, subtract, divide, raise to a power), solve algebraic and differential equations, generate natural logarithms and trigometric functions, A/D and D/A conversions, and frequency division.

For words of more than 4 bits, CD4089BMS devices may be cascaded in two different modes: an Add mode and a Multiply mode (see Figures 3 and 4).

In the Add mode som
