Philips Semiconductors FAST Products Arithmetic logic unit Product specification 74F181 FEATURES • Provides 16 arithmetic operation: add, subtract, compare, and double; plus 12 other arithmetic operations • Provides all 16 logic operations of two variables: Exclusive-OR, Compare, AND, NAND, NOR, OR, plus 10 other logic operations • Full look-ahead carry for high speed arithmetic operation on long words • 40% faster than ’S181 with only 30% ’S181 power consumption • Available in 300mil-wide Slim 24-pin Dual In-Line package DESCRIPTION The 74F181 is a 4-bit high-speed parallel Arithmetic Logic Unit (ALU). Controlled by the four Function Select inputs (S0–S3) and the Mode Control input (M), it can perform all the 16 possible logic operations or 16 different arithmetic operations on active-High or active-Low operands. The Function Table lists these operations.
