MC5474F181 Datasheet, PDF (1/5 Pages) Motorola, Inc – 4-BIT ARITHMETIC LOGIC UNIT

4-BIT ARITHMETIC LOGIC UNIT
The MC54/74F181 is a 4-bit Arithmetic Logic Unit (ALU) which can perform
all the possible 16 logic operations on two variables and a variety of arithmetic
operations. It is 40% faster than the Schottky ALU and only consumes 30%
as much power.
• Provides 16 Arithmetic Operations, ie, Add, Subtract, Compare,
Double, Plus Twelve Other Arithmetic Operations
• Provides all 16 Logic Operations of Two Variables, ie, Exclusive-OR,
Compare, AND, NAND, OR, NOR, Plus Ten Other Logic Operations
• Full Lookahead for High-Speed Arithmetic Operation on Long Words
