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 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,...
