The NTE4089B is a low−power 4−bit digital rate multiplier in a 16−lead DIP-type package 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. This device may be used in conjunction with an up/down counter and control logic used to perform arithmetic operations (add, subtract, divide, raise to a power), solve algebraic and differential equations, generate natural logarithms and trigonometric functions, A/D and D/A conversions and frequency division. For words of more than 4−bits, NTE4089B devices may be cascaded in two different modes: an Add mode and a Multiply mode. 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 for every 16 input pulses and the other unit will have 13 output pulses for every 256 input pulses for a total of 11/16+13/256 = 189/256. 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.

  • TA = −55° to +100°C, PD = 500mW
    TA = +100° to +125°C = Derate linearly at 12mW/°C to 200mW
