54F 74F181
4-Bit Arithmetic Logic Unit
General Description
The ’F181 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
Features
Y Full lookahead for high-speed arithmetic operation on
long words
Y Guaranteed 4000V minimum ESD protection
