MC14581B 4-Bit Arithmetic Logic Unit
MC14581B CMOS 4-bit capable providing functions Boolean variables binary arithmetic operations 14-bit words. level mode control input determines whether output function logic arithmetic. desired logic function selected applying appropriate binary word select inputs thru with mode control input high, while desired arithmetic operation selected applying voltage mode control input, required level carry appropriate word select inputs. word inputs function outputs operated with either active high active data. Carry propagate carry generate outputs provided allow full look-ahead carry scheme fast simultaneous carry generation four bits package. Fast arithmetic operations long words obtainable using MC14582B second order look ahead block. inverted ripple carry input (Cn) ripple carry output (Cn+4) included ripple through operation. When device subtract mode (LHHL), comparison 4-bit words present inputs provided using output. assumes high-level state when indicating equality. Also, when subtract mode Cn+4 output used indicate relative magnitude shown this table:
