Because of the symmetry of the add function, this device can be used with either all active-high operands (positive logic) or with all active-low operands (negative logic). When using positive logic the carry-in input must be tied low if there is no carry-in. Ordering Information PART NUMBER TEMP. RANGE (oC) PACKAGE PKG. NO.
