Abstract

This paper analyzes the 74LS381 ALU and designs its equivalent circuit. The 74LS381 ALU is arithmetic logic units(ALUs)/function generators that perform eight binary arithmetic/logic operations on two 4-bit words. However there are only little information to understand and design this circuit. Thus, we not only analyzed it but also designed an equivalent circuit to the 74LS381.
