DESCRIPTION HCF40181B monolithic integrated circuit fabricated Metal Oxide Semiconductor technology available packages. HCF40181B low-power 4-bit parallel arithmetic logic unit (ALU) capable providing binary arithmetic operations 4-bit words CONNECTION
logical functions Boolean variables. mode control input selects logical High) arithmetic Low) operations. four select inputs (S0, select desired logical arithmetic functions, which include AND, NAND, NOR, exclusive-OR logical mode, addition, subtraction, decrement, left-shift straight transfer arithmetic mode, according truth table. HCF40181B operations interpreted with either active-low active-high data word inputs function outputs using appropriate truth table. HCF40181B contains logic full look-ahead carry operations fast carry generations using carry-generate carry propagate outputs

four bits HCF40181B. HCF40182B look-ahead carry generator conjunction with multiple HCF40181Bs permits high-speed arithmetic operations long words. ripple carry output Cn+4 available systems where speed primary importance. Also included HCF40181B comparator output which assumes high level whenever four-bit input words INPUT EQUIVALENT CIRCUIT equal device subtract mode. addition, relative magnitude information derived from carry-in input ripple carry-out output Cn+4 placing unit subtract mode externally decoding using information table HCF40181B similar industry types MC14581 74181.
