Manufacturer:ROHM Description:Due to pin limitations the intermediate carries of the 283 are not brought out for use as inputs or outputs However other means can be used to effectively insert a carry into or bring a carry out from an intermediate stage Figure a shows a way of making a 3-bit adder Tying the operand inputs of the fourth adder (A3 B3) LOW makes S3 depen- dent ony on and equal to the carry from the third adder Using somewhat the same principle Figure b shows a way of dividing the 283 into a 2-bit and a 1-bit adder The third stage adder (A2 B2 S2) is used merely as a means of getting a carry (C10) signal into the fourth stage (via A2 and B2) and bringing out the carry from the second stage on S2 Note that as long as A2 and B2 are the same whether HIGH or LOW they do not infuence S2 Similarly when A2 and B2 are the same the carry into the third stage does not influence they carry out of the third stage Figure c shows a method of implementing a 5-input encoder where the inputs are equally weighted The outputs S0 S1 and S2 present a binary number equal to the number of inputs I1 C I5 that are true Figure d shows one method of implementing a 5-input majority gate When three or more of the inputs I1 C I5 are true the output M5 is true |
