MC10H181

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 4-Bit Arithmetic Logic Unit/ Function Generator MC10H181 The MC10H181 is a high–speed arithmetic logic unit capable of performing 16 logic operations and 16 arithmetic operations on two four–bit words. Full internal carry is incorporated for ripple through operation. Arithmetic logic operations are selected by applying the appropriate binary word to the select inputs (S0 through S3) as indicated in the tables of arithmetic/logic functions. Group carry propagate (PG) and carry generate (GG) are provided to allow fast operations on very long words using a second order look–ahead. The internal carry is enabled by applying a low level voltage to the mode control input (M). When used with the MC10H179, full–carry look–ahead, as a second order look–ahead block, the MC10H181 provides high–speed arithmetic operations on very long words. This 10H part is a functional/pinout duplication of the standard MECL 10K family part with 100% improvem...
