This device may be used to multiplier that provides an output pulse rate that is perform arithmetic operations (add, subtract, the clock input pulse rate multiplied by 1/16 times divide, raise to a power), solve algebrical and the binary input. For example, when the binary differential equations, generate natural logarithms input number is 13, ther will be 13 output pulses and trigonometric functions, A/D and D/A for every 16 input pulses. conversions, and frequency division. HCF4089B has an internal synchronous 4bitcounter, which, together with one of the four PIN CONNECTION September 2002
